Warner Brothers RecordsAfter twelve years together, The Mars Volta is breaking up.  Frontman Cedric Bixler-Zavala revealed the news via Twitter on Wednesday, tweeting, "I can't sit here and pretend any more. I no longer am a member of Mars Volta."

In a series of tweets that followed, Zavala writes that he tried to ?get a full scale North American tour going for [2012?s] Noctourniquet but [guitarist] Omar [Rodríguez-López] did not want to.?  The singer also cites López?s new side project, Bosnian Rainbows, as another reason for the breakup.  Zavala adds that he will be moving forward with a solo album, but did not give any indication as to when it will be released.

The Mars Volta released six albums during their career and won a Grammy for Best Hard Rock Performance for ?Wax Simulacra? from their 2008 album The Bedlam in Goliath.
