Ed,
i think you are not alone in your perspective on Jazz titles. there are 'rock' guys who want more classic Rock, Jazz guys like you, and hard core Classical guys......personally i like e'm all and actually look forward to expanding my musical hoizons. there is no wrong perspectives on music choices. and people moving in and out of tapes is normal.....and that happens for many different reasons.
the following is a quote from DocB (Dan Schmalle) from the Tape Project Forum.
I'm not a member over there so I'll add my comments here and folks can take them there if they wish. Three sets of tapes is 1.5% of our total licensed production capability of 200 copies (of which we don't have very many Series One titles left available). I don't think that is a particularly significant fraction in terms of being able to determine why the tapes are being sold. The simple fact is the economic crunch affected a lot of folks - though we seem to be coming out of that and subscriptions are really up lately. Earlier in the year we had very remorseful calls from a few Charter subscribers who were in financial straights and who could not renew for Series Two, and I can imagine those same folks might be the ones who were selling their Series One tapes.
so the selling of a few tapes on the goN is pretty much a normal occurance.
the big issue here is that if we are serious about allowing RTR to develop as an 'ultimate' format then all us tape-heads must support The Tape Project as best we can until the musical selections expand enough to become viable. once there are 30-40 titles out there then more fence-sitters will join in and the momentum The Tape Project began can sustain itself. we need a larger core of people wanting to hear the best possible sounding tapes. we don't need 2000 people, but 500--1000 would be enough that the various types of music will be reasonably represented and a person can get into tape and have the music that they want.
i think we are damn lucky that a group of people made the commitment to create The Tape Project. there is zero chance i would have got into RTR without them. to me it enriches our hobby having licensed legal master tapes you can buy and listen to.
