 In 2006 , <unk> <unk> signed with <unk> <unk> Records , recording their fifth studio album , Back 2 Base X. The album was intended as a return to the <unk> of rock music , and did not rely as heavily on studio enhancement as previous releases . The album was released on June 6 , 2006 , the same day as The Best of ( <unk> ) Planet Earth , a compilation album produced by <unk> Records without the band 's authorization or consent . Back 2 Base X peaked at No. 12 on the Independent Albums chart , and at No. 154 on the Billboard 200 . Allmusic 's Rob Theakston wrote that " Back 2 Base X suffers from the same problems as <unk> : it tries to be conceptual in thought à la <unk> and vicious in its political commentary à la <unk> or System of a Down , but somehow falls short by sounding like an angry <unk> on a <unk> . It won 't win any new fans , but existing fans of ( <unk> ) <unk> 's work won 't be turning their backs away from the band in anger <unk> soon , either . "
