yeah I can't blame him watching them either as every time I revisit them I remember something or pick something else up... either that or my head is just plain full so the more stuff I read and watch, the more the playdo effect takes place squeezing other stuff out!?
Again, I haven't seen the Pro Tools video but by the synopsis it does look like it takes a song from start to finish whereas Steve's dips in and out of background and specifics in the mastering chain, with some application as well, obviously.
As you're probably aware, videos on mastering and mixing are few and far between out there and they do tend to fall in to the 'black art' category of music production.... but, out of interest, is there anything in particular your son wants to know? Or is there anything in particular that you think your son should know, that could/ should/ would be covered in feature videos? Might be easier answering going about it that way??
