Just curious, because I'm based in the US and know little about cultures outside my own. I know bands like The Allman Brothers, moe., Phish, etc.. tour all over the world, so I know they reach plenty of people outside the US. I'm just curious if any bands of this genre have formed outside the US, and, if so, have any of them gained any popularity outside their country?
To further explain - The genre Jam Band typically refers to bands I've mentioned above. Bands who are known for extensive meandering improvisation, usually featuring a particular instrument out front and often with multiple leads. For instance, a song will begin (complete with lyrics), then proceed to where a guitar solo might be on their CD release but instead it turns into a 5 minute keyboard solo, followed by a 6 minute guitar solo, etc... They usually have a song they're working off of, and then will often turn that song into an extended instrumental jam (hence "Jam Band"). Some of the more popular bands (in the US, at least) in this genre are Allman Brothers, Phish, Grateful Dead, Blues Traveler, Widespread Panic, moe., Gov't Mule and Umphrey's McGee.
