WHEN THE COMPREHENSIVE HISTORY OF ELECTRONIC MUSIC is written, the period from the arrival of playable synthesizers in the 1960s and the introduction of drum machines in the 1970s until now will seem particularly disruptive. Synthesizers propelled the music out of academic laboratories and on the road to the diverse electronic space, ambient, and atmospheric genres of today. At the same time, drum machines propelled popular music out of the recording studio and onto the dance floor, where DJs produced an endless variety of complex beats that paved the road to EDM—Electronic Dance Music, and IDM—Intelligent Dance Music.
When the summer heat arrives, it stimulates rhythmic activity everywhere. Ironically, ambient is one of the few genres that can live without rhythm, but percussion is so fundamental to popular music that many ambient artists can’t resist using it. On this transmission of Hearts of Space, percussion-powered ambient for late summer, on a program called (with due respect to the song by Peter Gabriel) “RHYTHM OF THE HEAT.” Music is by AES DANA, VIR UNIS, STEVE ROACH, CHRIS MEYER’S ALIAS ZONE, EXTRAWORLD, BIFF JOHNSON, JOYSTICK, and THIERRY DAVID.
