As you mentioned, Dave had a drinking problem. While drunk he sometimes had public outbursts or otherwise did things detrimental to the band's image. He also got into arguments with other band members and (according to himself) even got into a fistfight with Hetfield.
Check out this article from Ultimate Classic Rock for details: 32 Years Ago: Dave Mustaine ...
Band with at least one instrumental song:
Ne Obliviscaris - Forget Not (Portal Of I)
Gojira - Dawn
Death - Voice Of The Soul
Death - Cosmic Sea
Obscura - A Transcendental Serenade
Hacride - Polarity
Opeth - A short list
Persefone - Zazen Meditation
Dream Theater - All their instrumental song!
Sepultura - Inquisition Symphony
Arch Enemy - Enter The Machine
Last.fm has a very good similar artists page for Dream Theater with over 200 bands/artist listed that range from extremely popular to barely known and has this for any bands/artist.
All the bands above are listed along with many, many other. Just a little taste of bands that are similar to Dream Theater on this page are:
Rush (2112 is a good place to start)
Muse (The 2nd law an easy one to get into)
Ozric Tentacles (maybe)

Your question can't be answered within few sentences. And it can't be answered by single persons alone. But I dare to write my share here, because I was and still am into several flavours of Metal including DM. And it was a significant part of my cultural development.
First I want to share some general opinions for which I do not have any proof whatsoever. ...
I'd suggest Haggard as a full symphonic band, with "Eppur si muove".
Septicflesh are using a lot of orchestra parts, you can try Titan, Communion and The Great Mass.
Dark Lunacy had a violin in Forget me Not and Devoid.
Fleshgod Apocalypse uses piano and various orchestration parts, I'd suggest listening to their Agony album.
Probably less symphonic than ...
You may want to check Edu Falaschi (ex-Angra) project called Almah. Their second album, Fragile Equality, has frequent parts of symphonic/orchestration keyboards with complex guitars riffs and progressive parts.
I also recommend you to check the Swedish Operatic Metal band Therion, most of their albums have complex orchestrations parts mixed with Power/...
You should look into Liquid Tension Experiment. It was an instrumental project of Mike Portnoy (then drummer of DT), John Petrucci (guitarist in DT), Jordan Ruddess (who became keyboard player of DT), and Tony Levin (King Crimson etc.). I'd say it's like the proggier parts of DT, sans vocals (hich is a plus in my book).
This is going to be a bit of a "list question" which isn't great for the SE format, but just for starters [& with no refs, just straight off the top of my head]...
The Beatles survived the loss of Stuart Sutcliffe - though at the time of his death he was no longer a member of the band.
The Rolling Stones survived the loss of Brian Jones.
Check out this link, you can try then to exclude certain metal styles and/or search more specific lyrical themes:
Btw, Black Metal seems the most prolific philosophical metal style :)
As user1556814 mentioned, this is a Song from System of A down, but on another album.
It is Track Number 7 of the Album 'Toxicity', called Bounce.
Could not find a studio version on youtube, but you can find some live versions:
Bounce - System of A down
the part used in your video starts around 0:22
I remembered it, because it is the track right after ...
I don't have time to verify, but I think the band is 'System of a Down'. Look at their main titles to check it out, especially in album 'Mezmerize' if my guess is correct:
System Of A Down - Mezmerize (Full Album)
Don't be fooled by the start of a song, because their songs are usually fluctuating, so the passage is probably hidden!
The first two lines probably go together in a sentence as “Fortune,
fame mirror vain” and can translate to “both fortune and fame mirror
what is vain.” So this basically says that fame and fortune reflect
false pride, or baseless pride. That one who has those things and
waves them around do so to express how proud they are, but ...
As both answers have noted, the long hair tends to go against social norms. Musicians have something to say, and one way to get noticed is to keep your hair long. Also, let's face it; chicks dig it. A lot of it has roots in the 60's, when men began to grow their hair long as a protest to "The Establishment". However, once fame and fortune are found, you'...
No Exit is really a terrible album to hear first as it doesn't sound much like old or new Fates. They didn't really hit on the more modern, more progressive sound until right after that album. You should try something later, like Parallels or Disconnected. Or both, as those two albums are very different from each other but will give you much more DT-like ...
When it comes to technical guitars one should definitely mention Rhapsody(now renamed to Rhapsody of Fire). Give Gargoyles, Angels Of Darkness a try. In their older albums Luca Turilli was playing the guitars and he is very talented guitar player. The band split in 2011 and now there are two bands - Rhapsody of Fire and Luca Turilli's Rhapsody.

The friend who played me the album remembered what I was going on about when he saw the question. The answer is Cooked on Phonics by Punky Brüster. The grumbly voice is doing the narrative in parts and the story is about the formation of a fake punk band from a metal one.
Hair length on men is generational and cyclical. In 40's and 50's America, short hair was culturally enforced. Hair length increased to a peak in the 70's, then reduced in the 80's, 90's and 2000's.
Musicians tend to be ahead of the cultural curve and to shape it. Because it came of age in the 60's, rock music became strongly associated with long hair. ...
Literally, it reads "V. A. Eye". Steve has been somewhat elusive on the whole meaning, but he did submit this answer to a question asked on his website:
“If you research metaphysics you will find mystical meanings for
pyramids and triangles, and the power of numerology and the number 7
being a prime focus. I had made many discoveries whilst I was ...
The weird thing about a tritone is that it isn't comprised of three notes, it's technically just an an interval of
three whole tones
...hence the tri tone
in other words, 6 semitones, an augmented [sharp ♯] 4th or diminished [flat ♭] 5th, between only two notes...
... which makes your above 2-note comparisons absolutely correct - each of those is ...
I would suggest:
Iron Maiden. They always had pretty thought provoking lyrics. The ones that come to mind immediately are the songs The Evil That Men Do and Rime of the Ancient Mariner.
Queensryche is also another group to consider. They dive into socio-political stuff more.
Keep in mind I am using a rather loose definition of philosophical here.
Uli Jon Roth is your man.
In his album Metamorphosis of Vivaldi's Four Seasons
he plays his version of Vivaldi's Four Seasons.
Also there is his album Prologue to the symphonic legends
in which he also plays some classical songs. Also check his live albums where he plays a lot of classical compositions arranged for electric guitar.
The closest example I can think of is the use of the "casket vocal track" in Black One by Sunn O))).
Scott "Malefic" Conner of Xasthur is claustrophobic so they decided his vocal contributions to "Báthory Erzsébet" would be best recorded (and enhanced with real feeling) by locking him inside a casket.
I ended up scrambling trough every album page on wikipedia. I didn't check singles.
These are the tracks that has someone listed as keyboardist\whatever.
Here are the results:

I think you should check the one-man-band (from Behold the Arctopus) project Direwolf:
Fist in Fetus are also technical and symphonic.
Therion, Nightwish, are symphonic, not so technical. Same thing with Haggard, Septic Flesh and Fleshgod Apocalypse, they are trully symphonic and progressive, but I wouldn'...
While not really the same genre, try Pelican. All their songs are instrumental, but they're not as metal as the songs of your example. I came to think of them when I thought of Call of Cthulu though for some reason, maybe due to the epic nature of their songs.
Coroner is a band that started out very metal though, and continued to progress, in the true sense ...
