as recommended to me from various sources:
cave in
minus the bear
spoon
many thumbs pointed vertically
Spoon is a great recommendation. A few years ago i started getting into indie music scene after being pretty disappointed with the future of main stream music. Spoon is one of those first groups you will come across when making that transition. I also recommend some of these other popular groups (none of them are too far out there):
Arcade Fire (these guys are the tops)
TV On the Radio (Black guys playing rock music infused with soul)
The Ponys (Mainly just their album this year)
Stephen Malkmus (Simple rock that isn't overproduced, i.e. Spoon. Former lead singer of Pavement)
Built To Spill (their most recent album is some real good guitar rock)
Cold War Kids (Rock, they are alright)
LCD Soundsystem (Dance/Punk, i.e. Daft Punks first album only with more vocals)
Tapes N' Tapes (Rock)
And if you are into Hip Hop, or if you ever were into Hip Hop, i highly highly highly recommend you get the album Deltron3030. It is an album that came out in 2001. I have not had a single person not like this album, even people not into hip hop or rap. The album is Beastie Boy Ill Communication, or Tribe Called Quest good.
For any of the above i recommend you go and check out their myspace pages (most groups have one). The Myspace pages usually have decent quality of their most popular songs. If you like any of these and want any other recommendations, PM me, or post up, i like to share.
