ATP is made up of Taata on lead vocals, Mug and Sugar on guitar, Kohei on bass, and Kaz on drums. They're a mixture of rock, psychedic music, and pop. I haven't found another Japanese band with quite the excitement and verve they and their music has.
They cite their influences as Siouxsie & the Banshees, the Cure, as well as The Beatles, etc. and it shows in their music. By that I don't mean they sound a lot like any of those bands, but they do have the same approach: find whatever makes a particular song work and use it-even if it breaks the rules.
Try a few songs. You won't be disappointed. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
