NEW YORK (AP) — More than 50 bands will help keep the party rolling for 24 hours during the O Music Awards.

The show put on by MTV, VH1 and CMT that celebrates music and counter culture will return June 19 with a 24-hour livestream event that will celebrate live music.

Ahmir ‘‘Questlove’’ Thompson will kick off 24 hours of live music by starting a drum-a-thon and artists will perform around the country. Awards in categories like next big scene, digital genius and best Web-born artist will be given out, and the festivities will splash across the three television networks as well.

The networks also will launch a ‘‘Make a Band Famous’’ opportunity through their artist platforms, beginning Wednesday.

Voting starts May 16 when a complete list of categories and nominees will be released.
