I'm a big fan of second wave Ska. Bands like Madness, the Specials and the English Beat early Police. I like some of the third wave and revival stuff especially the Bosstones and No Doubt (yes I like No Doubt).
Going to see English Beat and Reel Big Fish in July.
A cool Japanese Ska band Maryann. I got to see them at a live house in Nakano where one of the other bands on the bill did a cover of 99 Red Balloons.
