Remember when Tiger Woods … wait, actually: Remember Tiger Woods? He was a great golfer — one of the best ever — who dominated his profession for a decade, from 1997 to 2008.

Along the way, he would occasionally tinker with his swing, defying the old adage “If it ain’t broke, don’t fix it.” At the top of his game, Woods regularly looked for ways to improve, knowing that even if the tinkering set him back temporarily, it would pay off in the long run.

For the past couple years, Hobbs the Band has been one of the more dynamic musical acts on the local scene, a swaggering collision of brash blues-rock and shimmering space jams headlined by the prodigious guitar skills of its namesake, Hobbs Magaret. The band played killer sets at the 2012 Sisters Folk Festival and the 2013 Bend Roots Revival, with plenty of vaunted gigs at places like Silver Moon at The Belfry sprinkled in between.

But Hobbs has been tinkering. The band has expanded from a trio — Magaret plus bassist Pat Pearsall and drummer Kaleb Kelleher — into a quintet, adding Aaron-Andre Miller on keyboards and Jim Goodwin on saxophone and synths. According to Miller, the result is a “much thicker sound” that gives Magaret more room to shred. Goodwin, who experienced some success with the ’80s rock band The Call, says Hobbs the Band is becoming “a serious prog powerhouse.”

Sounds promising! Hobbs the Band is playing The Belfry in Sisters Friday, and Miller says they’ll be covering a classic album in full. Belle & Sebastian’s “If You’re Feeling Sinister,” maybe? Probably not. Just go and see what it is for yourself.
