I can appreciate the prog stuff and love to watch Tosin play and melt my brain. But I think I have a simple enough brain that I need a little bit of catchiness, and the crazy prog stuff starts to drown a bit for me. But I will give some of these a listen.I pretty much only listen to progressive music now. I can appreciate the old stuff but I get bored now if there aren't poly rhythms or shifting meters. Btbam is such an ocean of a band though, if you haven't listened to their last three or four albums you should give them a shot.
Tesseract, Periphery, The Contortionist, Opeth, The Mars Volta, etc are what really do it for me. The fusion stuff is incredible too. Haken, Plini, Caligula's Horse, Disperse, Animals as Leaders, Polyphia some really great examples of amazing guitar players and insane rhythmic sections.
I want to have more exotic tastes, but I guess my wheelhouse in metal was Rust in Peace. Enough technical stuff to keep it from being boring mixed with some really catchy riffs. Even though I play guitar and have tons of respect for the prog guys, there’s also some genius in creating a kickass ear worm riff.
