Born on July 13, 1942, Roger McGuinn became the founder, guitarist, vocalist, and guiding creative force behind The Byrds, one of the most influential bands of the 1960s. His signature 12-string Rickenbacker sound helped define folk rock and inspired countless artists, while songs like "Mr. Tambourine Man", "Turn! Turn! Turn!", "Eight Miles High", and "So You Want to Be a Rock 'n' Roll Star" reshaped the direction of popular music. McGuinn's blend of folk, rock, psychedelia, and country laid the foundation for genres that would flourish for decades, influencing everyone from Tom Petty and R.E.M. to countless jangle-pop and alternative rock bands. Few guitarists have created a tone as instantly recognizable as Roger McGuinn's chiming twelve-string.

Born on July 13, 1955, Mark Mendoza became the bassist for Twisted Sister in 1978 after previously playing with The Dictators.

His aggressive bass playing and larger-than-life stage presence were key ingredients behind anthems such as "We're Not Gonna Take It", "I Wanna Rock", and "The Price". Alongside Dee Snider and the rest of Twisted Sister, Mendoza helped turn the band into one of the defining hard rock acts of the 1980s.
