POULSBO — An 8-year-old Poulsbo girl being treated for a rare cancer will soon get a big boost from rock ’n’ roll.

Magic Carpet Ride, comprised of former members of Steppenwolf, will perform a benefit concert for Carmen Garringer on March 9, 8 p.m., at Envy Bar and Grill, 19559 Viking Ave., Poulsbo.

Tickets are $12 in advance, $15 at the door. Proceeds will benefit Caring for Carmen, a non-profit established to defray the costs of Carmen’s treatment for extraosseous Ewing’s sarcoma.

Also performing that night: Blacklist Union, a national touring band featuring Tony West of L.A. Guns.

Glen Bui, Magic Carpet Ride’s guitarist and manager, said the event will include a raffle of $5,000 worth of rock memorabilia — guitars, tour jackets — and Envy gift certificates.

Bui and the rest of the group devote most of their performances to charitable causes. A New Year’s Eve performance at One Ten Lounge raised $1,000 for Coffee Oasis. Magic Carpet Ride drew an audience of 500 to a 2010 concert in Saratoga, N.Y. to benefit an organization that serves individuals with disabilities and their families. More than $70,000 was raised. In 2009, Magic Carpet Ride (www.magiccarpetrideinc.com) played a special concert for the Thurston County Boys and Girls Club at the Great Wolf Lodge; the event raised more than $400,000.

“We’re really enjoying doing benefits,” Bui said. “We’ve all played the arenas and seen thousands of people in front of us. This is a better feeling. To walk away and know we’ve helped someone, even if one person, it’s the best feeling you can ever experience. It’s better than playing in front of 20,000 people.”

The concert is produced by Rock Steady Video Productions.

Donations can be made to Caring for Carmen at any branch of Boeing Employee Credit Union. Or send checks written out to Caring for Carmen to P.O. Box 804, Kingston, WA 98346.
