Seattle Peace Concerts hopes to raise its profile by resurrecting the spirit of Jimi Hendrix at Sunday's Hendrix Fest at Magnuson Park.

This should be a hot concert even if it isn't 80 degrees.

Seattle's Randy Hansen, known for decades for his blazing Hendrix tribute, joins the Leon Hendrix Mysterience (formed by Jimi's brother), Cafe Authors (featuring former Heart bassist Steve Fossen and British singer-songwriter Mike Curley) and local teen group Shotty for sets beginning at noon and continuing through 6 p.m. The free, all-ages event concludes with an all-star jam.

In staging the high-profile event, organizers hope to draw community support for Seattle Peace Concerts, which has staged free summer concerts at local parks for 28 years but has faced dwindling audiences and a dearth of new blood and new bands to carry on the tradition, even in a city teeming with musical talent.

Don Glenn, founder of the concert series, is now in his mid-60s and no longer able to produce the summertime event by himself. So a group of local music-industry professionals calling itself the Rejuvenation Committee has stepped in to revive the series and drum up community support. The committee is looking for sponsors, vendors and volunteers for future events.

"The Seattle Peace Concerts were once known and may still be thought of by some as a hippie fest," says Hendrix Fest co-producer Robin Fairbanks. "We're bringing this concert series into the new age."

Since there is little money to promote the Sept. 7 concert, committee volunteers have been handing out fliers at local festivals since May. Car Toys has lent the group its "Aftershock" stage free of charge, and Guitar Center provided the money for 15,000 fliers, as well as a Hendrix replica guitar that performers will sign. The guitar will be raffled off to help pay expenses.

"We're dedicated to reviving this 28-year-old tradition," Fairbanks said. "What a shame to have Don Glenn's vision of providing free music in the backdrop of some of Seattle's most beautiful parks die."
