Sleep Token seems to be Tool for a younger audience. Not exclusively, of course (I'm positive there is a lot of crossover appeal), but they tick a lot of the same boxes that Tool did/does, without the baggage of looking like it was made by the hypothetical listener's dad and his friends.
Now, I'm sure that this argument is reductive, and that mega fans of both bands could easily come in and explain how their music is worlds apart and yadda yadda yadda. I get it. In truth, I've not explored much of ST's catalog (just focused on exploring other sounds at the moment) but The Summoning absolutely slaps ass, and I don't believe anyone who suggests that they knew where that song was going when they listened to it the first time.
Mostly I'm invoking Tool because I feel like there are more parallels in their fandom than in their music. Alternative metal acts with progressive instincts who thread the needle between metal, rock, pop, and art to greater or lesser critical and popular acclaim. Both groups have a contingent of fans who won't shut up about how much they love the band, which leads to a certain counter-argument coalescing around people who are more sick of hearing about the band than they are actually upset by the band's music.
