3OH!3's Nathaniel Motte and Sean Foreman wanted to make a grand entrance for Tuesday's CD release party, so the band drove up to the University of Colorado's Fiske Planetarium in Banjo Billy's party bus.

The two returned to their hometown of Boulder to launch a new record, "Streets of Gold," before heading off for an appearance on Wednesday night's "Jimmy Kimmel Live." Loyal 3OH!3 fans lined up outside Fiske and cheered 3OH!3 as the band personally greeted the crowd.

Motte walked right up to a group of fans and greeted them with a warm, "How's it going guys?"

That's why about 200 fans were so excited to be at Tuesday's show.

Samantha Brook won tickets to the show via a Colorado Daily contest, and she was eagerly waiting in line for the event.

"It's my birthday, so I was excited to see the band," Brook said. "I like the band, because I like their beat and the music is so much fun."

That's a mutual feeling among 3OH!3 fans.

The band has turned its electro-pop music into an international phenomenon with the help of its very loyal fan base. The Boulder event was held as a thank you for local fans that pre-purchased deluxe box sets of the new record.

Foreman and Motte met as students at CU, and helped 3OH!3 grow from a hip-hop, party group to one of the hottest and most media-savvy electro-pop outfits around. The duo has worked with top-name acts Katy Perry and Ke$ha, and found a solid market for its tongue-in-cheek tunes.

The Boulder release party featured select tunes from "Streets of Gold" that were set to a pulsating laser light show. The songs showcased a more polished and mainstream-ready 3OH!3.

Then, Foreman and Motte performed live, energetic versions of new songs like "My First Kiss."

They also spent time thanking their local fans.

"It all started here at the Fox Theatre," Foreman said. "Thanks for supporting us and being from Colorado."

"Thank you for allowing us to do what we love to do," added Motte. "We really are appreciative of you guys and this fan base."

The next step is to see how far "Streets of Gold" takes 3OH!3.

Andy Schneidkraut owns Albums on the Hill and his business boomed with "Streets of Gold" pre-sales.

"For me it was like the gravy days of Dave Matthews and Big Head Todd," Schneidkraut said. "We sold a lot of pre-releases and there's a lot of interest in the record."
