That’s a tricky one because MWC has a fairly consistent style - fantastic if lacking a little bit of variation.
Of the one’s I’ve heard, I’d start with Somewhere A Fox Is Getting Married from 2011. Bang in the middle of MWC’s discography.
It sounds as if the later releases are slightly more techy, the earlier ones more hip-hop, and the beats all sound homemade. The dominant style is hauntological - full of eeries sounds, disembodied voices, library music and film/TV samples. It’s also playful in a way that a lot of Ghost Box stuff isn’t.
