Activism on behalf of music creators is the mission of the Recording Academy's ongoing Advocacy efforts, enlisting the support of our membership who best understand and appreciate how policy affects their livelihoods. Here are 20 artists, producers and professionals who have joined the cause and are also recognized this Sunday with nominations at the 61st GRAMMY Awards.
