When you go to a Luke Bryan concert, you're guaranteed to hear the Georgia native perform his down home country hits like 'All My Friends Say,' 'We Rode in Trucks' and 'Country Man.' But you also might do a little headbanging.

Luke has been known to throw a taste of metal into his live show, surprising his audience with a cover of Metallica's 'Enter Sandman.'

"It's a little out there! I hope [Metallica's] James Hetfield doesn't gun me down one day," Luke told The Boot with a laugh, after we saw him perform 'Sandman' at a recent show in Nashville. "I think it adds excitement to the show. The fans seem to love it, and they're singing right along."

Watch Luke perform 'All My Friends Say' and 'Enter Sandman' after the jump.

It didn't take much for Darius Rucker to convince Dierks Bentley to perform with him at the upcoming Homegrown Concert in his hometown of Charleston, S.C.

"He's one of my best friends in country music and one of the nicest people in the world ... We text all the time," Darius told Charleston's WEZL radio of buddy Dierks. "I asked him about this concert and he said, without hesitation, yes. We even changed the date on him and he said he didn't care. He's just the best."

The morning show guys at WEZL poked fun at Darius for gushing so much about his Capitol Records labelmate. And it turns out, they're not the only ones laughing at the singers' friendship.

She's way too young to remember Tiffany, but country singing sensation Katie Armiger is following in the '80s pop sensation's footsteps. The 18-year-old songbird has embarked on a mall tour (remember Tiffany's?), stopping at shopping centers in major cities across the country this summer.

Katie has teamed up with The Boot to bring us exclusive photos and commentary from her tour. This first photo (above) was taken just before her first mall stop.

"When they showed me the bus, I was blown away," Katie tells us. "It's one thing to see your name so large, but to have my face on the side was really amazing. It made me so excited that the tour is really going to happen! For the past three years, we've been living out of rental cars ... this bus is a dream come true."

Keith Urban has performed with an eclectic group of musicians, including Alicia Keys, Bryan Adams, Al Green and Justin Timberlake. The latest to join that diverse list are the Counting Crows, as Keith teamed up with the rockers last Friday at Wisconsin's annual Summerfest concert event.

Even Keith, who is a huge fan of the band, admitted it was a bit of an odd pairing -- but a great one. "Yeah, I guess we've got our own things going on," he told the Milwaukee Journal-Sentinel with a laugh. "It's just the way it happened ... We didn't know about it until the gig was booked. I'm thrilled. I love those guys. It's really just Summerfest and their imaginative pairing, which I think is killer."

Members of Little Big Town describe performing for their fans as an unbelievable rush. In order to have instant energy with their first song in a show, LBT's Kimberly Schlapman says the group gets together with band and crew right before they go onstage.

"We do this thing we call 'hands,'" she explains. "We all get together in a circle and pile our hands on top of each other and then say a prayer. Then we do this goofy thing that no one would understand."

"I'm a boating nut. If I told you how many boats I've had, you'd think I was crazy," admits country icon and boat enthusiast Alan Jackson. "I must have 20 woodies dating from the 1920s to 1960s. When you're out on the water in a classic old boat, it's as if you've gone back in time."

It's that love of boats that inspired Alan to throw an 'AquaPalooza' concert on Alabama's Lake Martin. The July 25 show is, of course, only accessible by boat.

"It's a fun show where everyone comes by water," Alan explains. "They get there at dawn and they're drinking and partying all day."
