Turns out the band has teamed up with Rock the Earth, Musictoday, Collective Good and Gibson to encourage fans to recycle their old cell phones.

The statistics on discarded phones are pretty alarming: One mobile phone has enough super toxic heavy metals to contaminate 40,000 gallons of drinking water. Worse yet, even though 1 billion new mobile phones were purchased in the U.S. last year, only one percent ever get recycled.

And besides feeling good about helping to keep toxic chemicals out of the environment, fans who bring in an old phone will get 20 percent off a future Musictoday purchase, be entered into a nightly drawing for an Instant Live soundboard recording of that evening’s show.

Fans redeeming phones will also be entered into national contests for a Gibson Guitar and the grand prize of a Party Like A Rock Star experience, which includes the use of a Gibson Tour Bus for a one night concert excursion with 12 friends.

“We’re very happy to align with Rock the Earth in this effort to keep mobile phones out of landfill, and just like everyone else, we too have been looking for the right place to recycle our old phones,” said guitarist Derek Trucks. “In fact, I plan on bringing my five old phones to the Rock the Earth booth and encourage everyone else to do the same.”

If you want to dispose of old phones, but aren’t planning to see an Allman Brothers show this summer, you can visit CollectiveGood.com/RockTheEarth to get an online entry form and take advantage of free shipping. All participants will receive the Musictoday discount and be entered into the grand prize drawing.
