See Zac Brown Band Play Joyous 'Tomorrow Never Comes' on 'Fallon'

Carpe diem anthem highlights the musical variety of the group's new album 'Jekyll + Hyde'

The eclectic Zac Brown Band highlighted the variety of their just released Jekyll + Hyde album, performing one of the new LP's deep cuts on The Tonight Show Starring Jimmy Fallon earlier this week.

"Tomorrow Never Comes," co-written by Brown with Niko Moon and frequent collaborator Wyatt Durrette, came off like a vibey hybrid of country, jam rock and just a hint of house.

The album has already produced Number Ones in country ("Homegrown") and rock ("Heavy Is the Head," featuring Chris Cornell), and Brown told Rolling Stone Country to expect as much back in November.

"Our boundaries have dissolved and we're going to still do things that are somewhat familiar that people like, but we're also going to stretch out and take chances beyond what we've done before," he said. "Some people are going to be really surprised."

On "Tomorrow Never Comes," the eight-piece crew puts acoustic guitars and an electric mimicking a banjo out front, but listen close at the end and you'll pick up faint whiffs of a pulsating synthesizer too.

Add that to the heady, carpe diem philosophy of Brown's lyrics, and the newly retooled group is showing off evolution far beyond their fresh John Varvatos threads.

Jekyll + Hyde was released Tuesday, while the summer tour of the same name begins May 1st in Nashville and runs through September 12th with stadium dates in Boston (Fenway Park), New York (Citi Field), Chicago (Wrigley Field) and more.
