Lonnie Mack, born Lonnie McIntosh on July 18, 1941, in West Harrison, Indiana, was a pioneering American guitarist and singer-songwriter. He played a significant role in the development of blues rock, Southern rock, and rock guitar soloing. Mack's early exposure to country, rhythm and blues, and gospel music shaped his unique style, which he began developing at a young age after trading his bicycle for a guitar.

Mack's breakthrough came in 1963 with the album "The Wham of that Memphis Man," which featured hit singles "Memphis" and "Wham." His innovative guitar techniques, characterized by aggressive, fast, single-string phrasing and use of the whammy bar, influenced many legendary guitarists, including Eric Clapton, Duane Allman, and Stevie Ray Vaughan. Despite his initial success, Mack's recording career waned with the British Invasion, though he continued to tour and perform.

In 1985, he made a notable comeback with the album "Strike Like Lightning," produced with Stevie Ray Vaughan, and continued to perform until 2004. Mack's contributions to music earned him recognition as one of rock's first true guitar heroes. He passed away on April 21, 2016, in Nashville, Tennessee.
