I'm mostly a 3rd waver, then 2nd, not so much old-school. It might be hard to find, but the ska-funk combination of Perfect Thyroid was one of my all-time favorites. They had a lead singer with a perfecly-clear baritone voice, three other guys who could sing well, good horns, and the drummer's rhythms were amazingly complex.
