You’ve seen artists toss guitar picks and towels and water bottles into the crowd. Luke Bryan gave away a microphone stand Wednesday night (July 20) in the middle of a one-hour show for the Samsung AT&T Summer Krush 2011 concert series.

Luke performed a high-energy, 12-song set at the Grand Ole Opry House in Nashville—and in all his running back and forth across the stage, he smashed into his mic stand a couple of times. So at show’s end, he picked up the stand and handed it to a fan and said, “You can have the piece of crap mic stand. Here, take it home with you.” The fan gave it back to the crew when Luke went to change for a few do-overs. But Luke got a Sharpie, autographed the mic stand and gave it back to the fan.

The other cool part of the night: Luke also did a mash-up of his breakout hit, “All My Friends Say,” and Metallica’s “Enter Sandman.” Luke hesitated just for a second, given the decades-long history of traditional country music played at the Opry. Then he muttered, “I’m sorry, Bill Monroe,” and plunged in, thrilling the 3,500-person crowd.
