The Rock and Roll Hall of Fame Induction Ceremony on Saturday (April 18) was indeed rocking, and Zac Brown contributed to the night by covering the Paul Butterfield Blues Band's "Born in Chicago" with Tom Morello.

Brown, Morello (formerly of Rage Against the Machine and Audioslave) and harmonica player Jason Ricci banded together for an absolutely fantastic and electric tribute to the legendary group. Their performance had everything: Brown's lead vocals, dueling guitars and top-notch harmonica playing.

"They always got the house on fire," the J. Giles Band's Peter Wolf said while inducting the Paul Butterfield Blues Band, "and played every night like it was the last night.''

Surviving Paul Butterfield Blues Band members Mark Naftalin, Elvin Bishop and Sam Lay accepted the award. Butterfield and guitarist Mike Bloomfield both died in the 1980s, so their families represented them at the ceremony.

"That was a butt-kicking band," Bishop said in his speech, "and we helped the blues cross over."

At the end of the evening, Brown again hit the stage for an all-star jam with Ringo Starr, another of the 2015 inductees; Paul McCartney, who helped induct his former bandmate; and many of the night's inductees and performers. They played "With a Little Help From My Friends" and "I Wanna Be Your Man."

Even though the Zac Brown Band are first and foremost a country band, they have gained attention from the rock community with their latest single, “Heavy Is the Head.” The track, from their upcoming Jekyll + Hyde album, earned them a spot on Billboard‘s Mainstream Rock Songs chart.

Jekyll + Hyde is scheduled to drop on April 28. ZBB will then kick off a summer tour on May 1 at Nashville's Bridgestone Arena.

HBO will air the 2015 Rock and Roll Hall of Fame Induction Ceremony, presented by Klipsch, on May 30 at 8PM ET.
