New single is great, I feel like they’re trying a bunch of new stuff here, with the more electronic sounding stuff going on in Among the Sleep and the rapping bits in Uncanny Valley, but they’ve still got that core ‘Zera’ sounds that I love so much.

I am dying to hear AtS live, I hope I’ll get the chance someday
