I understand the process all too well (I worked as an audio engineer in various studios around the UK for nearly ten years), and what disappoints me with remixing records in 5.1 is that it is a lot, and in many case a LOT of work that, from what I have heard, rarely yields enough to make it worthwhile. For live recordings? Yes, totally understand that. Totally. For studio albums, and perhaps its a very personal thing, but that I just don't understand. Its certainly not uncommon for the artist to not even involve themselves with the 5.1 mixing and to elect to simply approve the final masters.
And why should they? We're talking about creative people who are being asked to revisit things they did 30 odd years ago. There are very few creatives I know who would relish the idea of trawling over past works. Onwards and upwards is the attitude.
Record labels will, and historically have, tried every trick in the book to get the consumer to buy, over and over again, music that you already own and remastering / 5.1 / multi-format single release / new formats / bonus-tracks / previously unreleased tracks are all devices that make this happen. I can understand why an artist wouldn't necessarily fall over themselves to be involved with a retrospective cash-cow project when they could be working on new things.
I still haven't heard a 5.1 mix of a record originally released in stereo / mono that has made me think: "Yeah, this is it. I get it." That said, I'm certainly open to suggestions. I would like to be convinced otherwise.
Love? The band or The George & Giles Martin Beatles thing? Haven't heard it I have to say. Will endeavour to check it out.
All the best,
Derwood
