One of the most influential progressive metal acts of all-time. Many metalheads have enjoyed the band's work since the beginning. They have definitely laid their mark in music.
But sometimes Dream Theater isn't enough you know? So here are a couple of bands that I have selected for you to check out, that fans of Dream Theater may find some enjoyment in.
The main reason I made this list, these guys are so awesome and underappreciated. Check out their song Falling Back to Earth.
