Doors drummer John Densmore and guitarist Robby Krieger will also have vocal accompaniment from a variety of singers in what’s being billed as the two musicians’ first show together in 20 years. Furthermore, the 30-minute semi-acoustic set will host singers Micah Nelson, Haley Reinhart, and Dave Stewart of Eurythmics.

The January 23rd concert is part of a benefit event for People Assisting The Homeless, a California non-profit committed to building affordable housing and providing a network of support to those struggling with homelessness across the state. The evening will feature performances from Jason Mraz, Fitz and the Tantrums, Ingrid Michaelson & Maddie Poppe, and many more. Tickets and a full lineup are available on the event’s website.

This Doors reunion comes on the heels of another recent, high-profile reunion concert for charity. On January 4th, surviving Nirvana members Dave Grohl, Novoselic, and Pat Smear came together for a five-song set at the Heaven Is Rock And Roll gala at The Palladium in Los Angeles, CA. The bands’ surviving members were joined on stage by a rotating cast of singers, including Beck, St. Vincent, and Dave Grohl’s daughter Violet.
