Good news Colin, must feel good not to have all that around your neck any more.
“Music has always been a matter of energy to me, a question of fuel. Sentimental people call it inspiration, but what they really mean is fuel. I have always needed fuel. I am a serious consumer. On some nights I still believe that a car with the gas needle on empty can run about fifty more miles if you have the right music very loud on the radio”
Hunter S Thompson
Good for you Colin. Wish you well with your new ventures.
It is impossible for anything digital to sound analogue, because it isn't analogue!
