Oh prog metal, so many good ones. Here’s some you may or may not have heard of…
Spastic Ink – Ron Jarzombek of Watchtower kills it in this band, of which Ink Complete is my favorite of their two albums. Ultimate instrumental math metal with no comparison
Orphaned Land – Israeli band featuring loads of unique instruments and sounds from the middle east. Half if English, half in Hebrew, lucky for me I know both haha. Check out the album “Mabool” or the recently released “Never Ending Way of OrWarriOr.” Love this band
Spiral Architect – Only one album but it is a masterpiece. Really complex riffing/timing. Not a big fan of the vocals though
Fates Warning – Surely you’ve heard of them, but they’re often overlooked. “Awaken The Guardian” and “The Spectre Within” are amazing, and John Arch may be my favorite metal vocalist ever.
A few more are Gordian Knot, Ayreon, and Redemption. I could go on but here’s a super awesome link instead
BTW that site is having a tournament style best metal album of all time thing going on. Interesting to say the least
