Micheal Crichton wrote some early novels under a pseudonym. In one of them the character goes thru an unlocked door after his friend doesn't respond to the doorbell. He finds the friend sitting on the floor in a lotus position, motionless, turned away with headphones on. Upon approach, he see the friend steadily crying.
"What's wrong, what happened?"
"Nothing's wrong, I just listened to the Adagio d'Albinoni".
Probably was Gary Karr on double bass w/organ accompaniment. Cheers,
