The Mars Volta Will Not Rest!

So The Mars Volta's fourth studio album, Bedlam In Goliath, is out today - and already there's new material on the horizon in the form of yet another solo album from lead guitarist Omar Rodriguez Lopez.

Entitled Calibration, its released on the 25th of February and features contributions from Chilis guitarist John Frusciante, keyboardist Money Mark and TMV partner in crime Cedric Bixler-Zavala.

This confirms the band as one of the most prolific of our time, Four studio albums, a live album, and now five solo albums - its like the 70's all over again!
