For their latest single, London’s 4am Kru teams up with Bradford production duo McDonald & Jannetta. The result is “Pianos Raining Down” which as you may have guessed features a good amount of pianos along with 4am Kru’s famous drum & bass production. The most interesting part of the track is the tempo shift in it. Starting off at a blistering 165 bpm, a piano break 30 seconds in sees “Pianos Raining Down” slow to 134 bpm. It is not done trickily; the slow down is noticeable but the song keeps plugging away and is just as danceable.
