First guitarist was possibly Jimmie Webster, who made recordings in the 1950s using a two-handed tapping method he described in 'Touch Method for Electric and Amplified Spanish Guitar', published in 1952. George Lynch, from the bands Dokken and Lynch Mob, has claimed that George Van Eps used tapping in the 1950s as well.
As far as Rock goes, the earliest ...
There is no one technical reason for this, but there are some things that deal with the technology/requirements of the time when whole song fade outs were more popular.
Quoting from this NPR article on the subject:
"I'm pretty sure fade outs did not occur during the days when 78s were used ... since in those days music was recorded directly to disc. ...
That would be a Talk Box (the track referenced in your questions is listed on the Wikipedia page).
The gadget works by having a small loudspeaker linked by plastic tube to the musician's mouth, allowing the shaping of notes with the mouth, much as a singer would.
There is a nice clip on YouTube of Peter Frampton using such a device.
It's known as a side-stick or cross-stick

My vote for the 1st use of 1-handed guitar tapping would be Harry DeArmond:
My vote for the 1st use of 2-handed guitar tapping would be Stanley Jordan:
The Wikipedia article on Fade states that it is not possible to reliably identify the first modern recording to use fade.

Obviously, he was using guitar, but you are probably wondering what guitar effects he was using.
The main effect for "Machine Gun" live was a pedal called a univibe. He also used a FuzzFace-style pedal and a wah-pedal.
The univibe was invented as an attempt to imitate a Leslie Rotating speaker.
In the picture (from Woodstock) below, the pedals are (from ...
This is called a modulation, or more informally (as David indicated) a "key change." It repeats some or all of the song as transposed to a new key. It is very common in some styles of music (for instance, gospel music), and usually is used to add excitement or interest to a repeated section. Some songs only have one, but others have multiple modulations. ...
If all you have is the audio it's all about experience and recognizing.
You have to know the rapper's voice and be able to differ it from other rappers.
With videos it's a bit easier, because you may have seen the rapper in a movie or in the news before and recognize his/her face.
If you don't listen to a lot of rap you probably won't be able to recognize ...
Agree with Zach. In addition, some songs were played in concert Grateful Dead style with the song followed by an extended instrumental jam. In the record studio, the jam would be faded out just before a clam was played or the jam was running out of steam.
When the intro is faded in, this is for the same reasons only in reverse order.
listening to unknown artists, i frequently search for exact string matches of particular lyrics. it can be tricky to spell the lyrics as they were transcribed by others, and the text has to be long enough to be unique, but this is a very viable search strategy for looking up a particular rap.
