Astronauts is Dan Carney (previously of Dark Captain), often ably assisted by Michael Cranny. I’ve mastered both Astronauts albums – Hollow Ponds in 2014 and End Codes in 2016. It’s often a challenge to work on, as much of the music is very restrained and quiet, so there’s so much more to consider than overall volume. I find that with delicate music like this, if I’m not careful my mastering processing can end up changing the shape of the mix, which isn’t necessarily desirable.
