Roulette's Brooklyn housewarming proper wraps up with a local appearance by Cosa Brava, a bicoastal all-star avant-rock and improv unit that reunites two former Skeleton Crew bandmates, guitarist Fred Frith and keyboardist Zeena Parkins, melding their skills with those of violinist Carla Kihlstedt, percussionist Matthias Bossi, bassist Shahzad Ismaily and sound designer the Norman Conquest.
