Episode 143: Matt Rollings says his role as the leading studio piano playing sideman in Nashville from the late 1980s onward made it hard for him to forge his own taste and sensibility as an artist. Now that he's slowed that work and broadened his projects, he's made his first album as a leader in 30 years, Matt Rollings Mosaic, with a bunch of friends and collaborators who happen to be superstars, including Alison Krauss, Lyle Lovett and Willie Nelson. Our talk covered the fascinating ways and means of the A Team Nashville session players and much more. Also in the hour, emerging singer songwriter Shannon LaBrie, who's about to release an album produced by the guy who brought us The Judds and SHEL among many others.
