Boz Scaggs’ 1976 album “Silk Degrees” spun off an astonishing number of hit singles, including “Lido Shuffle.”

It’s hard to pigeonhole Boz Scaggs music.

It’s bluesy yet seeped in early psychedelic rock. There’s an argument to call him a soul man, and some have even ventured to say he has Southern rock accents.

All of his musical shades will be on full display Oct. 27 when he headlines the sixth annual Fox Tucson Theatre Foundation Chasing Rainbows Gala. The fundraising concert starts at 7:30 p.m. at the Fox, 17 W. Congress St.

Expect to hear Scaggs, 72, survey his extraordinary music career that started in the 1960s as lead singer of his childhood buddy Steve Miller’s namesake band. In the late 1960s, Scaggs went solo, landing his first true hits nearly a decade later with the 1976 album “Silk Degrees.” The album reached No. 2 on the Billboard 200, spinning off the hit singles “It’s Over,” “Lowdown,” “What Can I Say” and “Lido Shuffle.”

Expect to hear him sing those at some point Oct. 27. If set lists from recent concerts prove true, Scaggs’ show also will include “Georgia,” “Harbor Lights,” “Last Tango on 16th Street” and a cover of Aretha Franklin’s “Until You Come Back to Me (That’s What I’m Gonna Do).”

This is the sixth year that the Fox Theatre Foundation has hosted its gala fundraising concert. Past headliners included Emmylou Harris and Rodney Crowell in 2015 and comedian Martin Short in 2014.

Tickets are $75 to $300 through foxtucsontheatre.ticketforce.com
