Tetragrammaton Records was founded in 1968 by executives Doug Morris and Bob Krasnow, initially focusing on rock and pop music. The label gained prominence in the late 1960s and early 1970s, known for its eclectic roster. Key artists included the influential rock band Iron Butterfly, famous for their hit "In-A-Gadda-Da-Vida," and the folk-rock group The Electric Prunes. Tetragrammaton also released albums by other notable acts, such as the avant-garde composer Frank Zappa and the psychedelic band The West Coast Pop Art Experimental Band. Despite its initial success, the label struggled financially and ceased operations in 1971. Tetragrammaton's legacy endures through its contributions to the psychedelic and progressive rock genres, as well as its role in promoting innovative music during a transformative era in the industry. The label's catalog continues to be celebrated by collectors and music historians, reflecting a unique moment in the evolution of popular music.
