Swing and a Hit

Singer and guitarist Erin Harpe formed her Delta blues quintet in Jamaica Plain in 2010, and the group has been all over since then, winning the Boston Blues Challenge three times, playing the five-day International Blues Challenge in Memphis in 2015, and touring to support their debut album Love Whip Blues. With “a golden voice and guitar chops that dazzle” (Living Blues Magazine), Harpe and company bask in a vintage sound.

Erin Harpe & The Delta Swingers: Friday at 9:30 p.m. Theodore’s Booze Blues and BBQ, 201 Worthington St., Springfield. (413) 736-6000, theodoresbbq.com.

Blues Brothers

Round out your Delaney House dinner with music from Piper Hopkins Band, who deliver a kinetic fusion of blues, folk, rock, reggae, R&B, country, jazz, and soul. Local musicians Steve Piper and Carl Hopkins formed the band over a decade ago, but they keep it fresh by playing hard and playing often, especially through Hampden County and northern Connecticut.

Piper Hopkins Band: Saturday at 7 p.m. Free. The Mick at Delaney House, 3 Country Club Road, Holyoke. (413) 532-1800, logcabin-delaney.com.

Bands will include Pretty Daddy, Speak!, Mystics Anonymous, The Brass, Seth Newton, Rev. Dan & The Dirty Catechism, Starbird Bow, Tundra Toddler, SSP, and more. Wear purple and your dancin’ heels — and stick around for the raffle to win some rare Prince items. A portion of proceeds will be donated to the Epilepsy Foundation.

Gemstone Rock

Driving bass, complex percussion, dark melodic keyboards, and intense electric guitar leads define Springfield rock band Opel’s sound. They’ll be playing to fill the beautiful, high-ceilinged former factory space that is Brew Practitioners, as the bar pours beers brewed on-site as well as a selection of non-alcoholic drinks.

Opel: Saturday at 6 p.m. Brew Practitioners Brewery and Taproom, 36 Main St., Florence. (413) 584-2444, brewpractitioners.com.
