Bassist for The Lumineers, Ben Wahamaki got so into a live performance, he smacked himself in the head.

Wahamaki caused a bloody mess on stage when he hit himself in the noggin with his mandolin, but kept playing, according to contactmusic.com. In an interview with BANG Showbiz, the strummer said he hit himself in the head at one point during a UK show, continued to bleed, but kept going.

"I felt really weird and self conscious about it," he told the publication. "Our show is not the kind of thing where people bleed. It's hardly Slipknot.''

The Colorado-based folk five-some is made up of Wesley Schultz, Jeremiah Fraites, Neyla Pekarek, Stelth Ulvang and Wahamaki. Wahamaki joined the band in 2012, according to contactmusic.com.

They rose to quick stardom with their self-titled debut LP, featuring the songs "Ho Hey" and "Stubborn Love and continue to tour across the United States. The band already sold out many dates during the European leg of their tour and will return to play a few prominent festivals this summer.

Their album, "The Lumineers," that was released in April 2012, received two Grammy nominations for Best New Artist and Best Americana Album. Their hit single "Ho Hey" debuted at No. 90 on Billboard's Hot 100 chart, peaking at No. 3.

The group was also nominated for two Billboard Awards this year for Top New Artist and Top Rock Artist.

The lead single was also used in marketing for the blockbuster film "Silverlinings Playbook."
