Well, of course I am extremely thankful for all the help, suggestions and support I got from the esteemed members of this forum. I am sorry if it came off like I wasn't.
But, to be honest, there really isn't that much more to tell!
A guy and a girl from the label came round, I made coffee, we talked about the work they wanted me to do, paymnet terms etc. After a while we went into the studio and I started mastering the first track. The girl stayed in the lounge sketching (she's an artist/designer), and the guy watched and asked questions/made comments while I mastered two tracks for him. Then we all went for lunch and they went back to the train station where we said goodbye.
He was happy with my work, and played all the tracks I have mastered so far out live in a club last night. I haven't heard back from him since then.
As far as I was concerned, I felt a lot more pressure to "perform" than I normally do, which made me feel a little uncomfortable. It was probably a good experience for me, as I let him know what I was doing, step by step, and why I was doing it. And as they say, the best way to really learn something is to teach it (I should know that, I have been teaching for the last 11 odd years).
I agree with a previous poster who said it's the right of the artists to be there for the mastering session. But, for me personally, it felt more uncomfortable. Hopefully it will be something I get to try again, and my attitude/thoughts will become more positive with experience.
Not really sure there is much else I can say on the subject? Except thanks once again for all your support and interest!
