Appa (あっぱ) is a Japanese rock band formed in 2004 by Keitaro Izawa, Kazuto Satō, and Hideaki Hotta. Since Izawa is well grounded in jazz and classical music, Appa's musical features are influenced by them. The biggest feature of the playing style of Appa is Izawa's piano playing. Izawa, who is the leader of Appa, is one of the members of Tokyo Jihen (from 2005). Read more on Last.fm.
