Last March Suction Records released "Dopamine", an album of unreleased late 1990s recordings by obscure and arguably overlooked Dutch producer Erik Jong AKA RX 101. "Serenity", the sequel, was compiled from tapes of tracks recorded in the same period. It's a little different to its predecessor, offering creepier, drowsier melodies and far more robust, redlined beats - the kind of metallic, mutant IDM drums associated with the mid-to-late 1990s output of both Autechre and Aphex Twin. The quality threshold remains high throughout, making us wonder why Jong's inspired creations weren't released when he made them. Whatever the reason, it's great that we now get to wallow in his soon-to-be-classic 90s IDM treats.
