A little bit of Ska never hurt anyone now did it? ^_^
These girls take Ska to a new level with popish vocals, yet still keeping the instumentals to the Ska core. I was honored to see them at Warped Tour last year, they put on a great show. One of my favorites of the day and I didn't even know they would be there.
