Grown in Boston when its members were Berklee students, Lettuce (above) has been bringing the funk for more than two decades. During that time, the guys have kept busy with other projects, from guitarist Eric Krasno and keyboardist Neal Evans’ groovy organ trio Soulive to drummer Adam Deitch’s jazz chops with John Scofield and bassist Erick Coomes’ anchoring work with Dr. Dre. But Lettuce – which also includes guitarist Adam Smirnoff and horn players Ryan Zoidis and Eric Bloom – will be back in town on Friday, laying the grooves at House of Blues behind its latest album Crush, which stretches from hip-hop to psychedelia.

Singer/guitarists Mackenzie Scott and Ellen Kempner both churn melancholy, pointed lyrics in songs that surge with six-string eruptions in their respective indie-rock outfits Torres and (Boston’s own) Palehound, and they’ll team for a formidable double bill at Great Scott on Friday. Here’s a jump to my recent interview with Scott, along with a live clip of her performing as Torres.

Saturday offers country-blues from the veteran guitarist Paul Rishell and harmonica foil Annie Raines singing songs at Club Passim — alas, the Del McCoury Band has cancelled its Sanders Theatre show due to travel issues with the winter storm. And on Sunday (after the Patriots game), World Music/CRASHarts presents an eclectic indoor festival at House of Blues. CRASHfest will feature 10 bands on three stages, including Afro-pop dynamo Angelique Kidjo, experimental violinist Kishi Bashi, the percussive Dhol Foundation and even local stalwarts like the Ethiopian soul-pop ensemble Debo Band (below) and rootsy song-swappers Session Americana.
