Gangsters.

I tend to not like modern bands that claim to play ska, they simply don't have a feel for the music. I especially don't like modern bands that claim to mix ska with punk, because these bands tend not to have a feel for either genre. I like my ska older. Either give me some of the original 60's Jamaican stuff or give me the late 70's 2-Tone stuff.

And, speaking of 2-Tone, The Specials in their prime were quite good. [Links shamelessly swiped from the still slightly out of order gmtPlus9.]
