To be honest, I've held off from listening to anything new since Isaac left. I'm fucking judgy regarding vocalists and I just haven't been ready to give them a chance yet.
I really enjoyed the chaotic, wolf-parade-esque bursts from Isaac. If there's a particular track you recommend let me know and I'll check it out.
That's fair. Isaac was a huge part of their sound on the first two albums and they aren't the same without him. They're sharing vocal duties now.
From their Live at Bush Hall album I really like the songs "The Boy", "Turbines/Pigs", and "Dancers". The first two are sung by May. Her voice is a lot more delicate and it's a completely different sound than Issac but I think she sounds great. "Dancers" is sung by Tyler and she captures a little more of that energy that Isaac had but it's not quite the same. Still an enjoyable song though.
