O you cant forget unscandal if you like ska have you ever seen the opening for Scramble?
Some other bands I really like are The Pillows, Beat Crusaders, Boom Boom Satellites, Move, Peelander Z, Polysics, Sparta Locals, and Tsushimamire. O and my latest favorite 9mm Parabellum Bullet. I have been listen to all of them for a fairly long time, enough to see some of them in concert in the US and see other break up before I could see them. But last year I started branching out more and listening to just about anything that anyone else suggested and thats how I found many new styles that I really enjoy.
