This is the issue with being a TOOL fan. Nothing sounds quite like it. And Russian Circles is another favorite, but the algorithms are just like "this is clearly metal (it's not) so we'll put a bunch of screamy metal in your playlists that you'll obviously love" (screaming is annoying unless it's sparsely placed for emphasis)
I recently switched from Spotify to Qobuz and while I do like Qobuz, it lacks a block artist feature, making their playlists hit or miss.
