The septet Trey Anastasio tours with between Phish gigs are about as chops-heavy as his regular band, as this Atlanta gig shows. Anastasio's guitar rips (natch), and the horn section adds nice R&B color. But the reggae-fied "Windora Bug" is stoned and drooling, and it's unclear why Anastasio is moonlighting in a role so similar to his main one. He hands off vocals to trumpeter Jennifer Hartswick for a cover of Led Zep's "Black Dog" — a small surprise on a collection that could use more.

“Help Me”

Joni Mitchell wrote and recorded this song for her album Court and Spark, but she had to switch from her regular band to make the song sound exactly the way she wanted. "I had attempted to play my music with rock & roll players," she told Rolling Stone. "They’d laugh, 'Awww, isn't that cute? She's trying to teach us how to play.'" Mitchell switched to a jazz band, Tom Scott’s L.A. Express, and scored the biggest hit of her career in the process.
