I prefer The Murder Capital. Also from Ireland, kind of similar, but more my thing. I'm not a fan of the mix of DC, think his voice is much too far forward in the sound...
I actually prefer the newer singles to Dogrel. I think it sounds a little more produced but not in bad way. But maybe that's what people liked about it.
Maybe a hot take this, but I've got the first 2 albums, seen them live, and I'm still not convinced by Idles. I'd listen to Future of the Left 10 times more than I would them. Still, they are worth checking out for yourself though...
