Foo Fighters frontman Dave Grohl announced on Friday (September 28th) the launch of the Dave Grohl "Play" Reverb Auction in partnership with Reverb.com, the leading online marketplace dedicated to buying and selling musical instruments. The auction starts on Tuesday, October 9th, and will feature guitars, drums, and more signed by the musician. Proceeds from the auction will go to organizations that help young generations of musicians "just play."

In August, Grohl unveiled Play, a two-part documentary that ended with him performing a new solo 23-minute song on seven different instruments. Grohl created the project to showcase "the rewards and challenges of dedicating ones life to playing and mastering a musical instrument." In conjunction with the project, recording studios around the country donated session time to young musicians.

Grohl told us a while back that the most important thing is keeping the human element in music: "The most important thing is that there's a human element to what you're doing. With digital technology, it became a lot easier to manipulate these performances. I think what that does is it really takes a lot of personality out of music, you know. Like John Lennon didn't really sing perfectly in key and John Bonham didn't really play perfectly in time, but they just -- it felt great." in San Bernardino, California.
