The sensual guitar-based songs of Boston singer/songwriter Hana Kahn compel with their emotional nakedness and elegant musicianship. On the January-released “Venus And Mars” (streaming below), for example, the strong-timbered Kahn boldly details solitude and longing with guitar strums that excitingly add up to what can rightfully be called peaceful sonority. Perhaps like the most moving tracks in the singer/songwriter genre, Kahn’s subtly bold tunes seem personal but, impressively, can speak to many. Hana Kahn plays at Middle East in Cambridge, MA on 2/25.- Zach Weg
