Ska is an amalgam of reggae, swing, and surf-rock influences. 3rc wave Ska has punk influences. A walking bass, offbeat chords, repetetive drumlines, and brass are the most obvious ska traits. Offbeat lyrics and interesting voices are also trademarks. Skankers also have an affinity for Canada.
Ska freakin rox!
Five Iron Frenzy and The Aquabats are good Ska bands.
