Sons of Apollo is an American progressive metal supergroup formed in 2017 and composed of Mike Portnoy, Billy Sheehan, Derek Sherinian, Jeff Scott Soto and Ron Thal. Portnoy, Sheehan and Sherinian had already worked together at a short-lived, live instrumental project with Tony MacAlpine. Sherinian was asking Portnoy to be a drummer in a band full-time. Portnoy agreed when he had time for it.

Their debut album, Psychotic Symphony, will be produced by Portnoy and Sherinian (as "The Del Fuvio Brothers") and is expected to be released on October 20 via Inside Out Music/Sony Music.
