Based in Los Angeles, The Beta Machine’s McJunkins and Friedl are well known for their roles in the rhythm section of A Perfect Circle. The two first rubbed shoulders when they auditioned for Ashes Divide, led by A Perfect Circle’s Billy Howerdel. Recognizing a powerful creative bond that went beyond that band’s ranks, the duo was soon asked to join Puscifer, led by Tool frontman and APC co-founder Maynard James Keenan. Their associations still extend far beyond that cluster of bands.
