Thanks for everything Steve, the Masters are sounding HUGE! We really appreciate your technical expertise and working with us to reach our vision. I will definitely be recommending other bands I mix to go to you for the finishing touches! Cheers!

Programmer, Synths

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.

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.

Hey Steve – I’m impressed with what you have done with my song in such little time! It sounds way cleaner and the instruments have so much more room to breath. I also love what you did with the stereo imaging!

Steve Nagasaki, you are a beast at what you do. The tracks have come up brilliantly. Nagasaki Sound are without a doubt the BEST place to get your material mastered. Rates are incredible, quality is second to none, and Steve himself is an absolute pleasure to work with.

You sir, are a genius. You are the only engineer i’ve worked with that always gets my image and perspective of the song across the line at mastering time! It sounds like my mix, which is exactly what i wanted to hear! EXCEPT, it’s better! It’s got that top end brightness and definition and the low end is tight and not overly boomy! Cheers again, man. Will definitely have more stuff sent your way very soon! :)

Thanks Steve, both sound great!! I’ll definitely recommend you to anyone looking for mastering and you’ll hear from us again on our upcoming EP.


I tried out several mastering previews for this track and yours clearly stands out as the very best! I love what you did to the tune, that analog character was really missing, and that extra punch works really well… Thanks again. You sir, are now my go-to mastering engineer!


The EP is finally out :) We really appreciate your work and i hope to work again with you in the future. Thank you so much Steve! Have a nice holiday :)

The ‘So Long, The Deep End Awaits’ ep was mastered at Nagasaki Sound. The turnaround time, price, and quality were the best out of several samples we received.
