The five-piece band Aqua Timez rely on a traditional setup of guitars, drums, and a keyboard, but with these well-worn pieces they zip nimbly between styles. Breaking into the Japanese music scene via the piano-accented rock ballad "Ketsui No Asa Ni," they have gone on to charm listeners with similarly slow-building numbers, wherein strings and lead singer Futoshi's helium voice make the climaxes all the more dramatic. Yet they can pick up the pace too, whether by embracing reggae riddims or by pushing the tempo up on aggressive rockers powered by rapid-fire guitar riffs.
