BRASIL on Dr. Böhm Professional 2000 Orgel (1978) Thomas Vogt
No Multitrack/overdubbing recording - realtime performed and recorded

Even after all these years this "beast" is quite hard to master :-)
Its´not about the entire playing only - let´s say the other 50% you have to deal with is creating & modifying the sound in realtime (especially when not using the limited programmable sound banks)... and every single "mistake" you notice directly!

As more or less usual in a kind of of jam-style - not knowing what happens next :-)
Enjoy.
