Seriously, Aquabats concert was the best I've ever been to. And believe me, I go to shows a lot. The crowd's attitude, the band, the stage antics, everything was just amazing. In fact I've found that Ska shows usually have the most fun and overall kind crowds where I live.

Two third wave bands that make some real quality stuff are Streetlight Manifesto and The Planet Smashers.

Also, be sure to check The Skatalites for one of the original ska imports straight from Jamaica way back when.

And of course from the period between the two, The Toasters are pure class.

Finally for that foreign flair, Tokyo Ska Paradise Orchestra (SkaPara for short) make some really wicked stuff. Probably the best hornlines I've heard from the genre.

(btw, The Aquabats latest stuff (i.e. Charge!) isn't ska. The band basically switched genres (but the new stuff is pretty good too). Check out their first two CDs for the most ska goodness)
