It's taken a lot of blood, sweat and tears, but David Clayton-Thomas says his jazz-fusion band is back.

Blood, Sweat and Tears will bring its repertoire of hits and new songs to Wolf Trap's Filene Center July 1. "I don't want to sound pompous," says Clayton-Thomas, "but this band will kick you in the solar plexus."

During the band's heyday, Clayton-Thomas' lyrics and bluesy vocals powered such hits as "Spinning Wheel," "You Made Me So Very Happy" and "When I Die." But, says Clayton-Thomas, "I was burned out emotionally, physically, spiritually. During our most successful years many of us didn't have a home though we had very nice luggage."

After a five-year sabbatical, Clayton-Thomas resurrected the group two years ago. Among members of the present nine-piece band are guitarist Dave Gellis and trumpet player Steve Guttman. Clayton-Thomas says the band has always first and foremost been performance oriented. "We like to be eyeball to eyeball with people," he says.

Gary U.S. Bonds will open the show at 8:15 p.m. Tickets are $12 for lawn and $16 for in house seats. Tickets can be charged by calling 432-0200 or 800-448-9009.
