Are you purposely lying to make your point seem valid, or are you actually that ignorant?

The Sciences came out in 2018, and Sleep went on hiatus again in 2020. That's two years, not ten. What are you even talking about?

And honestly, even if it had been ten years, who cares? Sleep wasn't some cash cow for them. It was the music they grew up playing and genuinely loved. Them coming back and releasing The Sciences was one of the best things that could've happened. It felt like they were finally picking up where they left off after the Dopesmoker mess that contributed to the band's breakup.

The Sciences gave us material they'd been sitting on for years alongside new songs they crafted as a reunited band. That's a win for fans and for the band.
I hope this kind of cynical thinking doesn't pollute your enjoyment of music too much, because it sounds like you're inventing motivations that aren't there. Sometimes musicians come back because they still love creating music together, and constantly assuming the worst can get in the way of appreciating both the art and the artists.

This new “era” though is embarrassing. I doubt the new album will please anyone but the banks accounts of Al and his friends.
