Streetlight Manifesto is the absolute greatest thing to ever happen to ska.
They helped redeem an entire genre of music, after so many years of garbage pop punk "ska" poisoning the airwaves.
And considering Streetlight Manifesto is made up of members of Catch 22 and One Cool Guy, you should also check out those bands, and also, Bandits of the Acoustic Revolution (Streetlight unplugged).
RBF, The Aquabats, Less Than Jake, Big D, Goldfinger, Five Iron Frenzy, all garbage. Can't stand that stuff.
Streetlight for life!
