Guys! I'm 14 and I and a lot of my friends have much better musical taste than other people from my school...
I've only really recently been getting into great bands - my knowledge is limited, but I am ever learning.
ACDC, The Animals, The Beatles, Ben Harper, Black Sabbath, Cream, Dave Brubeck, Donavon Frankenreiter, The Doors, Eric Clapton, Eurythmics, Guns N' Roses, INXS, Jack Johnson, Jet, Jethro Tull, Joe Satriani, John Butler Trio, John Lennon, John Mayall, Led Zeppelin, Metallica, Midnight Oil, Nirvana, Pete Murray, Pink Floyd, Powderfinger, Rage Against The Machine, The Red Hot Chili Peppers, The Rolling Stones, Traveling Wilburys, Van Halen, Velvet Revolver, The Waifs, The Who, ZZ Top
(that's my current listening list...)
I think that Metallica, Powderfinger, and Velvet Revolver really cut it as new bands. John Butler Trio is a really great blues band - definitely worth a listen.
Jet are okay, but I think they rip off all the other bands WAY too much.
By the way, I'm from Australia
