I stopped buying most of these type of CDs a while ago. I did buy Oliver Standing Stone (yea, I know its not a comp.) on Prog Temple recently but was a bit disapointed. When the hardcore stop buying I wonder how long the series will go on for!
Most of this stuff is previously comped, album tracks or at least listenable on Youtube etc. And if it's not any of these then theres probably a good reason why!
Must admit I haven't bought any particles in about 2 years myself.
I haven't written them off as such and will probably pick up a couple from the recent series just to check in but not high on the priority list.
