Esperanza Spalding is signing her support for Planned Parenthood…

Los Angeles’ Old Style Guitar Shop has partnered with the nonprofit organization that provides reproductive health care in the United States and globally to raise money for Planned Parenthood.

Old Style Guitar Shop’s owner Reuben Cox has donated a Gibson CJ-165 acoustic guitar with 102 artist signatures, including that of the 32-year-old part-Latina jazz bassist and singer, who beat out Justin Bieber for Best New Artist at the Grammys.

Other artists signing the guitar include Foo Fighters, Lady Gaga, John Legend, Katy Perry, Mac DeMarco, Sia, Tom Petty and Ryan Adams.

Additionally, Cox is partnering with the organization for “7-inches for Planned Parenthood,” an upcoming series of 7-inch vinyl records curated to support reproductive health care and basic health services like STD testing and treatment, birth control and cancer screenings.

All proceeds from the vinyl collection will go to Planned Parenthood.

The guitar is part of a raffle, which can be entered by donating $10 to Planned Parenthood. The winner will also receive a bound book of the signees’ photos.
