The trio playing at Sub Rosa this Sunday night is not quite Miramar, the great RVA bolero group whose “Dedication to Sylvia Rexarch” was on multiple “best of” lists last year. But it brings together the heart of that bands distinctive, lovely sound: the brilliantly-matched vocals of Laura Ann Singh (Quatro Na Bossa) and Rei Alvarez (Bio Ritmo), complemented by the inventive keyboards of Marlysse Rose Simmons (also Bio Ritmo). With Singh now living in the Bay Area, and Simmons studying in Brooklyn, the next four weeks are a rare opportunity to see them together. On alternate weeks, starting on July 16, they play from 7-9 as an accompaniment to Sub Rosato- a natural wine pop-up. (With 5-7 sets on non-Sub Rosato weekends.) Expect a mix of boleros, Brazilian songs, and new music. And there will be some excellent wines.
