Here are a couple of tracks from some influential, avant-garde groups. Sonic Youth has an extremely unconventional, experimental sound (my son would say the experiment failed), but they were influential to so many bands that followed and had a huge following of their own. You can hear their influence in Wilco, Radiohead, and other alternative/experimental rock outfits. The track I selected is one of the easier Sonic Youth tracks to listen to. Like good scotch, it’s an acquired taste. I also included a White Stripes track from the same era, as a contrast to the musical styles of the early 2000 music scene.
