(Chach-e-yoh)A Jamband from Arizona. The band name is derived from the word chach which was created and used extensively by the band's rhythm guitarist, Chachi Marini. When thinking of a name for the band, Marini and Doucheth Bageth, the other wordsmith, combined daddy-o with chachi to make chachiyo, the daddy-o of chaches. The Chachmeister General approved the band name, and so it was.
Man, were you at that Chachiyo show last night, it blew my mind.
