Synth rockers Future Islands are doing their part to help out their home base of Baltimore, Maryland. The band just announced it is auctioning off a variety of items, all related to its recent appearance on the Late Show With David Letterman.

Last year, Future Islands' Letterman performance of "Seasons (Waiting on You)" went viral and helped introduce the band to countless fans, going on to become one of the most-watched clips in the 33 years of the late-night TV show. At last count, it's been viewed over 4 million times. Letterman's response to their performance was very enthusiastic, but online, it exploded. Relive the gig in the video above.

"I remember seeing a 15-year-old girl and her eyes just lit up, and these 70-year-olds were kind of looking around at each other, like, 'this is cool'," singer Sam Herring told The Guardian. "We were like: 'What the hell is going on?' These celebrities started retweeting it. Coldplay retweeted it."

The band recently returned to Letterman to perform "The Chase," which they dedicated to the city of Baltimore. Items from that performance are up for grabs on eBay, including the actual cue cards that Letterman used when introducing the band, singer Sam Herring’s tennis shoes worn on the show, an autographed copy of the Singles LP and a couple of rare singles and a signed art print.


All proceeds from the auction will benefit the Baltimore Community Foundation's Fund For Rebuilding Baltimore. With less than nine days to go, the bidding is sitting at $1,725.00. You can check out the action here.
