Classical music is not a stuffy relic of the past, and ballet is more than inflexible tutus and dead composers. That’s the ethos behind “Kaleidoscope,” a collaboration between Austin Camerata and Ventana Ballet. Four local choreographers and seven living composers assemble their own musical Avengers team, fighting against boring stereotypes with an exhilarating mélange of movement and sound. There will be five performances over Memorial weekend, each one opening their doors early to offer a kaleidoscope of colorful cocktails at the KMFA bar. Get swept away with this spectacular showcase. – Cat McCarrey
