I was looking for a mastering guy who could bring out the big sound we were looking for. Steve was extremely helpful and sent me several reference masters to make sure I got what I was looking for. The finished masters sound fantastic and I would recommend any hard rock/metal bands out there looking for a world class job at a great price to contact Steve.

The album’s a tribute to our computing heritage, evoking a classic era of electronica at the dawn of the home computing boom, epitomised by pioneers like Kraftwerk, Jean Michel Jarre and Tangerine Dream. It’s all done using software, but it has that warm, punchy analog feel – like it was recorded to tape circa 1980. That’s down to the work of our amazing mastering engineer Steve Nagasaki at Nagasaki Sound.
