Veteran Ninja Tune producer Fin Greenall signs his Sideshow project to London’s future beat-fostering Simple label. Both “Sound of Today” and “I Don’t Know Why” mix clipped, alarm-clock ticking kicks and snares with dusky, sunset-hued melodies, even a little blues slide-guitar. Like former production partner Hefner, Greenall’s sound is uptempo narcotic, like a bag of hash for the dancefloor.
