If you're not familiar with the "Back to Mine" series, Wikipedia defines it as "a series of mix albums, usually (though not always) mixed by renowned DJs or composers of electronic music. The compilations usually feature artists other than the artist compiling the album, and are based on what the artist would play at home after a night out, rather than as part of a nightclub session." The newest in the series, Back to Mine 25, was done by these guys, and that is why Röyksopp is today's Band of the Day.
