Peter,
I am not an accomplished musician but I had been thinking of playing at some of our retirment/nursing homes for no pay, but only to share the enjoyment of music.
Forget the magazines negative response to your performance. I will bet that the majority of your audience appreciated you music.......except for those that fell asleep....had nothing to do with your music but with age. Dearly wanted to see the Presidental Debates last night..........oh well we have newspapers.
Keep a stiff upper lip and keep playing.
