Founded in 1973 in the Los Angeles area, Ya Ho Wha 13, otherwise known Yahowha 13 is a psychedelic rock band fronted by Father Yod, spiritual leader of a religious cult/commune called the Source Family. Ya Ho Wha without the vowels and spaces reduces to YHWH, the tetragrammaton. The band recorded nine LPs full of their extreme psychedelic sound with tribal drums and distorted guitars, some of which were completely unrehearsed jam sessions, others which contained more conventional rock songs. Members of The Source Family, who lived in the Hollywood Hills in the early 1970s, decided to fuse their musical talents and spirituality by forming an improvisational, psychedelic music group. They began to press LPs in 1973, most of which were recorded after hours of meditation at 3:00-6:00 a.m. in a soundproofed garage that served as the musicians'' studio at the family''s communal residence.
