Four Tet will take you on a journey through the world via many genres of dance music and a lot of weird underground foreign things. While not necessarily one of the most technical DJ's out there, he has musical tastes that are essentially unparalleled today. Lots of weird, spacey, out there dance music with typical Four Tet greatness mixed in.
I'd expect something like this, except for (potentially?!?) 3+ hours long. On the best speakers known to electronic music. This is going to be fucking incredible.
