The Canadian Broken Social Scene has been around for a while, but I only stumbled upon them playing with the machine at Rasputin. Apparently they earned a reputation as a pop act after 2001’s Feel Good Lost, but You Forgot It In People is more indie/experimental. I’m not sure you can be considered anything but experimental when you have eleven different musicians contributing. 2005’s self-titled album (packaged with the bonus EP To Be You and Me) is quite an adventure as well.
Favorite tracks: Cause = Time (YFIIP), Handjobs for the Holidays (BSS)
