American guitarist and vocalist, whose stylistic approach has ranged from rock & roll to pop standards and Latin music. His rock sound is exemplified in songs such as his 1962 hit "Let's Dance", which reached #4 on the Billboard Hot 100. When his early music's popularity began to fade, he switched to a more traditional role as a popular singer of soft ballads, scoring a hit with "Call Me" in 1966. He has also recorded in Latin styles. Over the intervening years, he has continued to work in all three modes.
