ACIDMAN is a rock band from Japan. Its members are Oki Nobuo, Sato Masatoshi, and Urayama Ichigo. Guitarist/vocalist, Oki Nobuo is the main composer for the group, and is always experimenting with new types of music. Even though their music can be very relaxing, they tend to be catigorized under punk. Simply put, the band has a sound that is unique. They are known for their "second line" series in which they take some of their rock songs and rearrange them to be jazz or bossa nova-like. Front-man Oki Nobuo also has a pharmaceutical license.
