Nope. Savath & Savalas is a project of Scott Herrin from Prefuse 73. The latest record is actually done in Spanish, featuring vocals from a girl from Barcelona, where Herrin spent some time recently. The whole thing's got a kind of Brazillian/Latin vibe, really laid back with a mix of acoustic and electronic instruments.

Nothing heavy at all.

If you want heavy, I did recently start listening to Texas Terri and the Stiff Ones. I've seen her described as a famale Iggy Pop. I can go with that. Thrashy trashy stuff.
