We already know that... 6 is Spanish flamenco singer. The most popular. 13 was born in Memphis and (I believe) he's more famous than Jimmy Angel. 25 is 62 years old and he was born in New Orleans
I think @vamborules already got it - your use of "unfortunately" made me think it was a bad thing that he was still alive- sorry for the misunderstanding
1 plays a Stratocaster in the picture, but he was a master of the Telecaster sound. 12 is an American singer-songwriter. 13 was a rock & roller (al least at the beginning of his career) born in Memphis. 15 is a post-punk band from Perth. 19 is a jazz pianist associated with people like John Zorn 25 is 62 years old and he was born in New Orleans (Do you know a TV series called "Treme"?) Clues everywhere.
