The Lumineers have sold millions of records and played stadiums around the globe. Their latest album is all about the pain of addiction and what it's like to see a loved one struggle with substance abuse. The band members share the personal stories that inspired the music, and play stripped-down versions of three songs, including the hit "Gloria." It's an intimate live episode recorded in front of an audience of people in recovery at the Clocktower Cabaret in Denver.
