7:30 p.m. The Joint. $20.
Thursday night, as part of its monthly Argenta Acoustic Music Series, The Joint will host the renowned Brazilian jazz singer and guitarist Badi Assad, who was born in Sao Paulo and grew up in Rio de Janeiro. She's performed with Yo-Yo Ma, Bobby McFerrin, Joe Cocker, Sarah McLachlan and Seu Jorge. She has been recognized as one of the world's best guitarists by Guitar Player magazine, and Jon Pareles of the New York Times has cited her "imaginative virtuosity, moving from gauzy delicacy to vigorous propulsion, from dreaming to dancing and back." In performances on YouTube, she fingerpicks on a nylon string guitar, while also humming complex melodies and simultaneously performing a kind of mouth percussion (clicking and thumping, more or less beat-boxing). It's pretty gripping.
