Jeff Goldblum has played jazz piano nearly every week in Los Angeles for 30 years. He and his band, the Mildred Snitzer Orchestra, started the gig in the 1990s, mostly unadvertised. His debut album, The Capitol Studios Sessions, hit number one on the Billboard jazz chart in 2018. As a teenager in Pittsburgh, he cold-called cocktail lounges from the Yellow Pages for gigs. The Jurassic Park star is a genuine jazz musician.
