Zac Brown Band's 2015 album Jekyll + Hyde, included "Heavy Is the Head" a collaboration with Chris Cornell.

In a 2015 interview with Nikki Sixx, Zac said, "It's an honor to have Chris on this tune, and he's one of my favorite rock screamers ever."

Chris was found unresponsive in his Detroit hotel room last night, following a show at the Fox Theatre. A representative has called his death "sudden and unexpected" and explained that Cornell's family will be "working closely with the medical examiner to determine the cause."

As news started to break, Zac Brown Band posted this message on twitter this morning, sendings his thoughts to the family.
