January 3. Besides their leader's being a musician of devastating dexterity, mandolinist Matt Flinner and his trio are bold performers, to say the least. Formed in 2006, the ambitious acoustic newgrass crew (Flinner plus Ross Martin on guitar and Eric Thorin on bass) has assigned themselves the challenge of writing new music for nearly every show they play, a project they've dubbed "Music Du Jour." For this engagement at the Rosendale Cafe, the group will be joined by none other than jazz guitar great Matt Munisteri, for whom they will custom-pen much of their second set's repertoire. (Lara Hope & the Ark-Tones rock 'n' roll January 14; the Irka Mateo Trio visits February 5.) 8pm. $15. Rosendale. (845) 658-9048.
