I've long felt that while Underground Radio was well mixed, it wasn't well mastered. In fact, it wasn't mastered at all. Mastering is a separate phase of production during which a talented engineer listens to your album and makes adjustments to the overall sound, as opposed to the individual tracks.
It turns out that at least some of the mastering process can be automated through the use of artificial intelligence, machine learning and other buzzwords. So I used a nifty automatic service called LANDR. I think the songs came out punchier and louder. You can listen to the remastered songs here at rock-opera.com, over at SoundCloud or download them from Box.
All of this was done in advance of preparing the music to be distributed digitally on iTunes, Spotify, Amazon, Deezer, Pandora, Google Play etc. I will be using CD Baby for distribution once I finish reviewing these.
