I was reffering to the music reproduced by entierly mechanical devices - most instruments, particularly acoustic ones, are of course macanical devices. But I really enjoyed both performances; being from Europe, I heard (of) them for the very first time. Both are reather poorly recorded, but playing of the Long Beach is WAAAY better. I can only *imagine* what sentimental value must a memory like this have to you. Well done, Sir !
