If you're looking for Bay Area-style thrash with bits of crossover, check out the fist-pounding metal mayhem of California's INTERNAL CORROSION. Chunky gallops bound with killer metal riffage and vocals that sound nearly identical to Aversion's Christian Fuhrer has netted me in as someone who thinks this music completely rocks.
Yes, many out there in grumpy-pants land could label Internal Corrosion as just another unoriginal thrash band, but there are too many parts in their music that absolutely shine, making these guys bona fide genre ass-kickers. Hector, Internal Corrosion's vocalist/guitarist, has a dynamic voice that is freakin' perfect for heading a thrash metal band. On top of that, the guitar solos are great, the rhythm is tight as hell, and the production on the available songs I've heard is stellar. I love it!
