I worked on the (Stem-)Mastering with Matthew on the new record of his band "Eternal Winter" and it was my pleasure. Great guy. He is very demanding and knows what he wants but he is also super open for input and suggestions, which is important. So we were literally squeezing out the last 0.5 dbs of finetunings till perfection :-)
The Record is awesome, very creative and you can tell that a lot of work went into it.
I'll work with Matthew again any time! :-)
