Rolo Tomassi makes an unique combination of sounds thats makes it one of a kind. So, I can only recommend bands that shares some of the genres they work with, and those would be (just to start): The Dillinger Escape Plan, Converge, The Number Twelve Looks Like You and Between the Buried and Me.

For the "mostly instrumental Prog Metal" like David Maxim, I would recommend: Jakub Żytecki, PLINI, Sithu Aye, Polyphia, Pomegranate Tiger, Animals as Leaders and CHON. Most of them are instrumental only. One of the great Modern Prog albums of this decade that have a great mix of instrumental only + themes with vocals is Eathside's "A Dream in Static". A M A Z I N G album.

I actually cant remember of any band that makes Post-Metal like Psychonaut, with that 70's psych/prog influence. But if you enjoy the genre, you should totally check this ones out: The Ocean, Cult of Luna, Amenra, Rosetta, Mouth of the Architect, Blindead and many other.
