i recently got an ipod and that revived my interest in music... i'd like some recommendations on a band (or two or three...) that can "shock" me with a type of music/sound unlike any i've heard. several points: 1) i'd like recommendations. please don't hijack the thread and start arguing about other people's recommendations. and no snobbish attitude please. i'm quite open and also believe popular != bad. 2) let's stick to rock/alternative (whatever that means these days) and techno/electronica. no classical, country or "serious" jazz. no rap/r&b or pop. 3) availability on iTMS a big plus because i'd like to be able to sample songs before purchasing. (via iTMS or otherwise... iTMS is a really handy preview station.) background: my current fav's: radiohead, chemical brothers bands i've liked for quite a while (but are quite "commercial"): dave matthews, u2, rem bands i'd like to get to know better: floyd, rolling stones the last band to "shock" me was chemical brothers a few years ago. i really like their stuff and i'd love to get some rec's on that genre of music. (techno/electronica -ish) thanks!
