[Editor's note: For our May issue's summer festival section, SPIN spoke with a number of artists on the festival circuit, from Gaslight Anthem and Metric to Doves and Jane's Addiction. Among them is neo-soul songstress Erykah Badu. Here, she tells us about her favorite moments backstage and waxes on music's power to bring people together.

I met TV on the Radio at Austin City Limits last year -- theirs was the only set I got to see. I hung out on the side of the stage, and afterward we exchanged info. I did more research on their work, and they on mine, and we decided to work together. Same with the Mars Volta -- I met them at a festival, and they ended up playing on my album New Amerykah Part One.
