With singles to their name on Toko and Urbantorque, Manchester’s Atomfunk selected L.A.’s Deepfunk for their latest release of classy, mature house music. Echoing the work of Salt City Orchestra, Attaboy and Dealer’s Choice, “Boogie Down” resounds with warm chords, thick bass and strong melodies. Flip for a pair of less dubby but equally friendly cuts primed for the onslaught of summer.
