Nicki Bluhm and The Gramblers jam to fame in their van

(CBS News) The Internet has opened new roads to success for lots of new artists. One group that has benefited is Nicki Bluhm and The Gramblers. They've turned YouTube into their own special venue, drawing a huge following as they rolled on down the highway.

The San Francisco-based group is often going between cities and decided to start making videos in their touring van.

They started out just posting the videos online for their friends, but last year their version of "I Can't Go For That" caught the attention of Hall and Oates, who tweeted it out to their fans.

"And then it was like crazy," said Bluhm.

The video went viral. It's been viewed well over two million times on YouTube. Bluhm said it has changed things a lot.

"We haven't stopped working since that happened," she said. "We had to upgrade to a bigger van. Had to get a trailer too, you know."

Nicki Bluhm and The Gramblers will open for the Steve Miller Band later this month.
