The combination of electronica and bossa nova often causes me to conk out in my caipirinha. But Brazilian singer Cibelle marries the warmth of Rio with the chill of the Eighteenth Street Lounge, and her music doesn’t cause me to enter REM-stage sleep. Cibelle’s self-titled debut is groovy and detailed, so you can stand up and sway to the bossa nova, samba, baião, and trip-hoppy beats or sit down, slap on some headphones, and get lost in the album’s gentle, psychedelic timbres. Her voice is a jazzy purr—a smoother, less tortured version of Portishead’s Beth Gibbons—and Cibelle’s melodies are dreamier than a white-sand beach. If her album doesn’t immediately win you over to modern Brazilian music, perhaps another caipirinha will. Cibelle seduces you along with La Fatcha at 8:30 p.m. at the Iota Club & Cafe, 2832 Wilson Blvd., Arlington. $12. (703) 522-8340. (Christopher Porter)
