The Ace of Cups – I Wanna Testify

The Ace of Cups was an American rock band formed in San Francisco in 1967. It has been described as one of the first all-female rock bands.

The members of the Ace of Cups were Mary Gannon (bass), Marla Hunt (organ, piano), Denise Kaufman (guitar, harmonica), Mary Ellen Simpson (lead guitar), and Diane Vitalich (drums). Lead vocals were sung by all members of the band except Vitalich, and all five sang backup. The songwriting, too, was divided among the band members.

As one of the first all-female rock bands, they were considered a novelty and never gained mainstream success, despite critical acclaim.
