The single "Drunk in Love", featuring Jay Z, peaked at number two on the Billboard Hot 100 chart. In April 2014, after much speculation in the weeks before, Beyonce and Jay Z officially announced their On the Run Tour. It served as the couple's first co-headlining stadium tour together. On August 24, 2014, she received the Video Vanguard Award at the 2014 MTV Video Music Awards.

Question: By the late 80s, House had moved West, particularly to San Francisco, Oakland, Los Angeles, Fresno, San Diego and Seattle. Los Angeles saw a huge explosion of underground raves and DJs, notably DJs Marques Wyatt and Billy Long, who spun at Jewel's Catch One, the oldest dance club in America. In 1989, the L.A. based, former EBN-OZN singer/rapper Robert Ozn started indie house label One Voice Records, releasing the Mike "Hitman" Wilson remix of Dada Nada's "Haunted House," which garnered instant club and mix show radio play in Chicago, Detroit and New York as well as in the U.K. and France. The record shot up to Number Five on the Billboard Club Chart, marking it as the first House record by a white artist to chart in the U.S. Dada Nada, the moniker for Ozn's solo act, released in 1990, what has become a classic example of jazz-based Deep House, the Frankie Knuckles and David Morales remix of Dada Nada's "Deep Love" (One Voice Records/US, Polydor/UK), featuring Ozn's lush, crooning vocals and muted trumpet improvisational solos, underscoring Deep House's progression into a genre that integrated jazz and pop songwriting structures a feature which continued to set it apart from Acid House and Techno.
