Sons of Apollo have cancelled their European festival appearances this summer, but on a brighter note they have added a handful of German dates to their tour docket.

"Due to unforeseen circumstances beyond our control, Sons of Apollo regretfully has had to cancel all remaining Summer Festival appearances at Wacken Open Air and Prog In Park II," the band says in a statement. "We sincerely apologize to all of the fans that were looking forward to these appearances."

The group has also moved their headlining show in Budapest, originally scheduled for Aug. 18, into the fall schedule. The gig will now take place Sept 17. All tickets for the originally scheduled August date will be honored at the rescheduled performance.

The collaborative effort Sons of Apollo came when former Dream Theater members Mike Portnoy and Derek Sherinian teamed up with Portnoy's Winery Dogs bandmate Billy Sheehan, guitarist Ron "Bumblefoot" Thal and vocalist Jeff Scott Soto. Back in the fall of 2017, they released their debut LP, titled Psychotic Symphony, and early this year embarked on their inaugural tour of the States.

We talked to Portnoy and Sherinian when the album came out, with the former revealing the genesis behind Sons of Apollo, calling it his, "dream lineup."

"I think that when we first put the idea of the band together, we thought that it would end up being mainly that kind of sound and style," the drummer said. "But I think maybe once we brought Bumblefoot and Jeff Soto and Billy on board, it ended up going to so many different places. And now when I think you listen to the end result, it goes way beyond the prog metal kind of tag or the Dream Theater comparison that we, so what we would inevitably have I think now transcended that. I think you listen to the album as a whole and it’s going to way more places than that."
