This mix was recorded at Apple Music’s first-ever New Year’s Eve party, a sweaty, strobe-lit celebration of house music at a cavernous warehouse in New York. Tim Sweeney, a veteran New York City DJ and longtime host of the taste-making radio show Beats in Space, which now airs exclusively on Apple Music and Apple Podcasts, closed out the evening with a joyful set of house and disco cuts from around the world.
