Who? Grace Stumberg, vocals/guitar; Bob James, guitar; Michael Petrino, bass; Josh English, drums.

What?: At 23, Stumberg already has several years of touring behind her - including traveling Europe as a member of Joan Baez's entourage - and the experience rather viscerally informs her sophomore effort, "Affect." Favoring a looser, more groove-oriented vibe than her 2010 debut, "To Whom It May Concern," disc No. 2 also finds Stumberg displaying a more seasoned world view in her lyrics. The disc, recorded by the eminently able Justin Rose at GCR Studios, is fluid and often funky, with longtime collaborator James lending harmonic commentary to the graceful dialogue between Petrino and English.

What's next?: A CD release party is 9:30 p.m. Saturday in the Sportsmen's Tavern (326 Amherst St.). Admission is $10.
