Every recording artist has that moment at the end of making a record when it's time to get it mastered. This was the first time that this process was done by someone other than the mixing engineer, since this time the mixing engineer was me, myself, and I. Metropolis Studios online mastering offer was the service that I decided on. They are based out of London, so they have to compete in the same space as Abbey Road Studios, which is no easy feat. But they have been doing it for thirty years, which says something. I have no regrets about going to them to finish my record. They took my record to places that I could not. Like the runner on the las leg of a relay race, they brought me in for the big win. If you want quality mastering done by a real person, Metropolis Studios is the way to go. I posted the link to their website below. Check them out!!
