By the time Infectious Grooves released Mas Borracho in 2000, the band had morphed into something like Suicidal Tendencies two, with many members from vocalist Mike Muir's initial, more serious, but sonically similar musical partnership.

On this, their fourth release and first in six years, Muir and company lay back more than at any time in the past, widening their stylistic and dynamic reach while maintaining the party atmosphere.

It's all about the funk on agile numbers like "Lock It in the Pocket" and "Good Times Are out to Get You," but since they're never content to stay in one place too long, the group drops some hyper-speed 64th note riffs ("Just a Little Bit") and a little space cowboy ruminations ("21st Century Surf Odyssey") that don't only defy the funk/metal categorization, but can't be adequately described by, or compared with, any genre at all.

Fans of Infectious Grooves, Suicidal Tendencies, funk-metal, and anything experimental in rock (e.g., Primus, Ween, Frank Zappa) will do well to check out Mas Borracho: a lickety-split, hybrid rocker's thrill-ride.
