aquabats like streetlight, hardly. (but they were the supporting act for the aquabats last time i saw em in december, they were awesome)
they started as surf/ska stuff (think dick dale mixed with... madness, and devo)
then their 2nd album was... i dunno, a bit less surf but still ska
their 3rd and 4th are like happy oingo boingo, not that oingo boingo wasn't happy, they were just a little dark.
then their 5th is more like... happy modern rock/punk with synthesizers, because all their horn players have left

.
but they're workin on a new album (and a tv show) right now, and it's supposed to be more like their middle stuff, so i'm way excited!
