Ats Commons hosts the three best-known professional theatre groups; the conservative Theatre Calgary, the more adventurous Alberta Theatre Projects (ATP), and the downright avant-garde One Yellow Rabbit Performance Theatre (OYR). The facility has two additional theatres, so other companies often produce shows here. Of special note is OYR's High Performance Rodeo festival, which runs for January and provides a wildly eclectic mix of performing arts (and performance art). Arts Commons is also home to the Calgary Philharmonic Orchestra which presents everything from buttoned-down traditional classical music to pops to symphonies for children. Finally, Arts Commons is the venue for many other concerts and events throughout the year.
