Rule No 1, when posting about an artist you have just discovered, never ever reveal that you have just discovered him/her.

If you do, you will inevitably trigger off a multitude of knee-jerk responses from people who can't wait to reveal that they have known for years, drank with, or went to school with, said artist .

Best to say something along the lines of ..."just heard XXX's latest CD , he/she is sounding better than when I first heard him/her over 20 years ago ..."
