Today's mystery yearbook photo features a Mexican-American rock guitarist, born July 20, 1947, who is known for his DNA-distinct tone. His namesake band fused blues, Latin and jazz, and in essence, he pretty much created his own genre. He's that good! He also added congas and other atypical instruments to rock music, which is among the reasons why he is so revered.

He returned to commercial prominence in recent years by pairing up with modern rockers like Nickelback and Matchbox 20's Rob Thomas. His music also inspires women's shoes. They are fashionable and the range of shoes is named after him. So he sort of has a foot fetish!
