There’s really not a lot to say here. Obviously mixing is a key element of the recording process. It is also something that is very hard to explain, as every session is different.
Black Tree offers, what we call a post record option. This is a Mix only package, that means; you record & we mix (and obviously master if required). We know that plenty of people these days own there own DAW software, enabling you to record a large majority of your material at home. But often where the process tends to fall a bit flat, is in the mix. Studios spend a large amount of money on their equipment, probably far more than most people can afford. This option is adapted by a lot of musicians these days.
