Every day, somewhere in America, a musician steps up to the microphone in a public radio station's studio and gives the sort of intimate performance that you'd never see in a concert hall. Given that the annual number of these special recordings climbs well into the thousands, the concept of the studio session felt ripe for a Top 10 list.
So we asked 10 of our partner stations to name the No. 1 favorite session they witnessed in 2013 and pinpoint the song that sent the most shivers down spines. Don't be surprised if you find yourself liking these versions more than their original recordings. They're that good.
