Well, many of them are composed of two kinda different styles that compliment each other, you can hear that in Clint Eastwood, in Dirty Harry, in Stylo, in Empire Ants and also in Saturn Barz. There are also Albarns vocals which have a bit of a sleepy, ethereal quality to them which lend a certain contrast to those of wh9ever they're working with, if they don't take center stage, like in Andromeda. They're also that lush but also somewhat detached sounding instrumentation lending the songs a bit of a otherwordly quality. And that's kinda contrasted by these more straight forward hip hop beats that have always been a pretty big part of their music.
Of course they've also made a lot of songs that don't exactly fit into that scheme but most of the ones we've heard seem to fit in pretty well with their work as a whole.
