Austin's official slogan is The Live Music Capital of the World. Austin has a vibrant live music scene boasting more music venues per capita than any other U.S. city. Austin's music revolves around the many nightclubs on 6th Street and an annual film/music/multimedia festival known as South by Southwest. The longest-running concert music program on American television, Austin City Limits, is videotaped on the University of Texas at Austin campus. Austin City Limits and Waterloo Records run the Austin City Limits Music Festival, an annual music and art festival held at Zilker Park in Austin. Other annual events include Eeyore's Birthday Party in April and Carnaval in February.
