Up until now, I've been listening mostly to classic rock (Led Zep, the Who, Beatles, etc... a lot of it). I love it, it's great and all, but I need diversity! I enjoy the occasionnal flamenco and Irish folk music, but never on a regular basis.
I recently stumbled upon Televators by Mars Volta and LOVED it! That stuff friggin TRIPS! I listened to some of their other songs on Youtube, and loved them all.
So, I'm pretty sure this band is unique in its style and playing, but...

What other bands would you suggest that resembles them in some ways?(different, pushing the boundaries, innovative etc.)
