Sons of Apollo are a progressive metal supergroup founded by ex-Dream Theater members Mike Portnoy and Derek Sherinian; its lineup also includes Billy Sheehan (Winery Dogs, Mr. Big), Ron "Bumblefoot" Thal (ex-Guns N' Roses), and Jeff Scott Soto (ex-Journey).

According to Portnoy, Sons of Apollo came together organically. He and Sherinan reunited shortly after he left Dream Theater in 2010 in an all-instrumental touring band with Sheehan and Tony MacAlpine called PSMS. It was their first time working together since the '90s. Though designed as a one-off, the band toured during 2012 and 2013. In the aftermath, Sherinan pursued Portnoy to create a full-time band. Given Portnoy's intense schedule, it took nearly three years. In late 2016, other members were recruited and the idea became reality.

Psychotic Symphony
Sons of Apollo's debut album, Psychotic Symphony, was issued in 2017 by InsideOut Music. It was produced by "The Del Fuvio Brothers" (as Portnoy and Sherinan were affectionately dubbed during their tenure together in Dream Theater). The concert album Live with the Plovdiv Psychotic Symphony followed in 2019.
