I must say I've been through this entire thread and there are some very interesting lists and bands I've seen, such good taste in here, some I'm not such a fan of but ANYWAYS! Here are my favorites!...:
Tame Impala
MGMT
Grateful Dead
The Allman Brothers Band
Railroad Earth
The String Cheese Incident
Mew
Yes(mostly the early stuff)
The Beatles
classical music, so far I'm liking Chopin and Vivaldi a lot!
Miles Davis
Herbie Hancock
...honestly I like a lot of jazz in general as well so i won't even bother to list' em as I'm still checking a lot of jazz in general
Nickel Creek(except their first album lol)
Led Zeppelin
...there so many other artists/bands I wish I could name, needless to say, I LOVE a lot of 60's/70's music and any modern indie stuff possibly, like Super Furry Animals or something, like I said, I'm still exploring.
Here's my last.fm profile if anyone's interested at my music listening history(you may be surprised lol):
