A diverse, deceptively busy weekend for concerts. Friday leans toward jazz with the broad harmonic palette of forward-thinking New Orleans trumpeter Christian Scott aTunde Adjuah at Scullers, the jazz and classical-bridging solo ruminations of Boston-based pianist Donal Fox at the Regattabar, and the sleek jazz-funk grooves of the popular group Snarky Puppy at House of Blues. And on the other side of the map, the acclaimed California singer/songwriter Tom Russell nestles into stark, literate cowboy-country tunes at Club Passim on Friday behind his new album Folk Hotel.

Two local rock fests take over opposite ends of the city on Saturday. Starlabfest 2017 brings such bands as Paul Collins & the Dazies, the Lyres and Black Beach to the Somerville Arts Council’s ARTfarm, while the free JP Music Fest brings a slew of groups including American Echoes, Diablogato, Love Love and Rick Berlin to Pinebank Field on Jamaica Pond.

Saturday afternoon also finds country-rock renegade Charlie Daniels making his annual stop at Indian Ranch, while the night presents dawn-of-’90s local favorites Buffalo Tom (pictured) celebrating the 25^th anniversary of its great album Let Me Come Over at Royale and R&B/pop trio Bell Biv Devoe headlining a free “Unity Concert” at City Hall Plaza to benefit Houston schools (bring classroom supplies). Other Saturday options include shoegaze-era English rockers Swervedriver at the Brighton Music Hall and co-founding B-52s singer Cindy Wilson at the Middle East Upstairs, taking a break from the quirky new-wave repertoire of her longtime outfit to fly solo with her own intriguing “turbo chill” electro-pop group.

In turn, eccentric rocker Kevin Barnes has recently been delving into electronic pop and cross-dressing (if cross-dressing seems like a tame theatrical move next to past exploits like riding a horse onstage) with his band Of Montreal, so expect some alluring frivolity when the group takes the Sinclair stage on Sunday.
