Scaggs produced two more platinum-certified albums in Down Two Then Left and Middle Man, the latter of which produced two top-40 singles "Breakdown Dead Ahead" and "Jojo".
After a hiatus for most of the 1980s, he returned to recording and touring in 1988, releasing Other Roads and later joining The New York Rock and Soul Revue. Scaggs opened the nightclub Slim's, a popular music venue in San Francisco. He has continued to record and tour throughout the 1990s, 2000s, and 2010s, with his most recent album being 2018's Out of the Blues.
Scaggs is credited for helping the formation of Toto. For his 1976 album, Silk Degrees, he hand-picked musicians after taking suggestions from several people. These musicians were David Paich, David Hungate, and Jeff Porcaro.
