“Infinite Fire” by Flying Colors. I only learned about the band today, although it features some musicians I know and love from other bands (including Neal Morse and Mike Portnoy). This track is a prog mini-epic, clocking in at only twelve minutes. But I can summarize it in one word: Wow!
There are also lots of live versions on YouTube just waiting to pop up in your search results.
(By the way, why are so many prog musicians named “Morse”?)
