The t-shirt I am wearing in today’s comic is for a band called Polysics. They are basically a Japanese DEVO on speed as you can see here and here and a little bit here. I really recommend checking them out.
If you are into Japanese music I would suggest checking out a show called Octopus Army which airs every Monday at 5:00pm EST on 93.3 CFMU FM (Listen on the web at http://cfmu.mcmaster.ca). It covers all aspects of Japanese music and is a good start if you are interested at all.
