In-demand Danish DJ/producer Christian Nielsen walks the tightrope between house and techno with the greatest of ease. With a discography consisting of productions and remixes for labels including Noir, Toolroom and Glasgow Underground, Nielsen makes a welcome return to Jesse Rose’s Play It Down imprint with “Beginning To End.” The raw, sinewy track out on July 8 oozes with unbridled funk and a ginormous bassline. Summertime house jams don’t come any finer than this.
