New electronica label Boltfish Recordings have done the sensible thing and released a compilation representing the artists on their label. Usually an excellent way for the curious to pick out favourites from a diverse range of talent, 'Mercury Sales' initially seems like a set of tracks from the same group of people, all of whom harbour a love of cool, techno music. It's decent stuff but lacking the emotional impact of the very best of the electronic acts. Five tracks in, though, the signs of greatness appear courtesy of Mint's 'Sleeping Giant' which shares a warmth and an air of mystery with Boards Of Canada. Zainetica and Mescalinaeden make similarly haunting contributions whilst Line Noise offers superior chill-out, J.Auer makes a good case for a drum and bass revival and The Rumblist excels with the multi-layered and highly tuneful 'Ickle Mewgul'. With twenty releases now under their belt in less than two years, long may Boltfish continue to evolve.
