Demi Lovato, Backstreet Boys, The Lumineers, Troye Sivan and Brandy Clark have joined forces with the MusiCares Foundation to support its grassroots social media campaign, the #MusiCaresChallenge, which is raising funds for its critical assistance and healthcare programmes aimed at supporting members of the music community in times of need.

The campaign encourages artists and fans to post a photo or video with their favourite album, using the hashtag #MusiCaresChallenge, and to make a donation to MusiCares.
