Born in Osaka in 1962. Lives in Hyogo prefecture. Isohata started playing guitar at the age of 12 and fell in love with jazz. From '82, in Tokyo, he studied various subjects including music theory, and from '85 was a student of the late Masayuki Takanayagi. His music ranges widely, from classical and popular to noise and abstract. His improvisation, with its abstract jazz and contemporary classical approaches, achieves both delicacy and boldness through visual imagery and distinctive theory-based formatting.
