NEW ORLEANS (AP) -- Longtime Grateful Dead drummer Mickey Hart came to New Orleans with a message for thousands of attendees at the AARP's national convention: Music has therapeutic powers.
Hart spoke about the importance of music and playing instruments. He led a drum circle with hundreds of drummers at the convention, which ended Saturday.
Hart and neurologist Adam Gazzaley a professor at the University of California at San Francisco, spoke about research showing music has a positive effect on the brain and how playing music can help offset the mental declines of aging.
Throughout the convention attendees could stop into a music-making pavilion.
