That IS very cool...
Honestly I imagined Mark's new album to be in a vacuum tube USB format, after all British Grove makes their own tubes. Would be so cool!
But all hard core fans can get, is a standard box set and digital downloads for WAV. I hope they would catch this idea. What could it be?
Guitars USB stick is too obvious and already taken for concert recordings. I can't come up with something, the tube is ingenious!
