Erol Alkan invites two of electronic music's most exciting producers to expand on both sides of his first solo single in five years, 'Spectrum' and 'Silver Echoes'. Techno-mastermind Matrixxman adds serious pressure to 'Spectrum' on his remix, upping the tempo and utilising the original's halcyon synth line to create a high-energy version with moments of pure sensation. One of the most original and promising underground producers of the last few years, Machine Woman delivers two contrasting reimaginings. Going deep and psychedelic on the 'Minimal Machine Woman Remix' of 'Silver Echoes', and then on the 'True Machine Woman Remix' reversing the tempo entirely, reinventing the melancholy cut as a erratic freakout.
