burke,
I hope I didn't come across as nasty but rather I attempted to give a larger perspective of what is really occurring with Instant Live.
The idea of instant music is great and being that I have recorded concerts and live music for 22 years or so, one I really appreciate. When done properly it is a win/win for everyone. However, the method it is being done by Clear Channel is ultimately not in the best interest of anyone but Clear Channel.
BTW, The Dead only started offering live versions of their shows during the summer of 03 and in doing so their turn around rate has been 2-6 weeks. They have never offered instant recordings. Rat Dog, on the other hand, Bob Weirs band, offered instant versions during the Spring of 04. Phil and Friends were posting free down loads of selected shows starting in 02 but again, they weren't available for sometime.
Most of the recordings I've heard that come from such source are "just" okay! They offer the purchaser or fan a copy of the show they attended with FM level sound. What I mean by FM is that for the most part the sound is compressed with washed out timbres, often less than engaging sound. Listener fatigue usually sets in quickly.
The concert goer maybe able to over look this in an attempt to relive the enjoyment of the show but if you weren't there or your not a hard core fan of the band you may not give them many listening. The learning curve for quality sound is still leaning to quantity for sales instead of quality of sound.
To be honest it is difficult since for the most part they are mixing an 80% board with a 20% ambient. The Board mix is usually mixed for the house, which often means that the Board feed is not very well suited for direct playback, thus the ambient mix. However, for ambient they usually place either 2 omni's on stage or two Cards at DIN or ORTF at the board and the board is not usually placed in the best spot for sound. Sometimes the mix has little to no ambience, which makes for a very dry sound.
That being said, though, if I'm unable to record the show myself, which has happened only a few times over the last 22 years, I would be glad to buy whatever was being offered. Yes, I may have a strong opinion but I do love the music I go out to see.
