Back when it was all you could download for ten bucks a month, while looking for stuff for my husband, I got some Roy Clark songs recorded long ago, including Under the Double Eagle. Wow. He goes over the tune, then revisits it with more and more ornamentation until he is playing faster than I believed possible. The there was his rendition of The Great Pretender. Amazing and funny. Now, I just bought an album of his. I am really impressed with his talent and his muic and his patter is good too. I never realized that he was anything other than run of the mill. I now think he is anything but.
What artists did you find have more talent than you realized at first?
