Beginning on Friday (April 17), fans around the world will have access to 48 hours of non-stop streaming performances from artist's living rooms, backyards, private studios and hometowns on LiveXLive.com and its apps, as well as on TikTok and LiveXLive's TikTok account.

"Music Lives" will also host quarantine-relevant programming tied to wellness, mindfulness, health safety and more self-care tops from leading experts and artists, with fans able to chat and share with other viewers during the broadcast. "The world, including the music industry, has been turned on its head over the past six weeks," Dermot McCormack, president of LiveXLive said in a statement.

"Community and connection are at the heart of live music and it's our mission with Music Lives to bring that heart to the comfort of people’s homes around the world during this time of ‘social distancing.' It's uncertain how long these circumstances will last and this multi-day, multi-genre festival can become more than a one-and- done event to an extended period of meaningful programming. Together with TikTok and these incredible artists, we’ll unite our global village with music."

TikTok's North American head of music partnerships and content operations, Corey Sheridan, added, “TikTok is proud to partner with LiveXLive to create an immersive, multi-day live-stream experience on our platform with #musiclives and to support artists, songwriters, and music professionals through MusiCares.
