Lonnie McIntosh (born July 18, 1941), known by his stage name, Lonnie Mack, is an American rock, blues, and country guitarist and vocalist.
Mack was born in Dearborn County, Indiana. In the early 1960s, he was a key figure in transforming the role of the electric guitar to that of a lead voice in rock music. Best known for his 1963 instrumental, "Memphis", he has been called "a pioneer in rock guitar soloing" and a "ground-breaker" in lead guitar virtuosity.
In 1963 and early 1964, he recorded a succession of full-length electric guitar instrumentals which combined blues stylism with fast-picking country techniques and a rock beat. These recordings are said to have formed the leading edge of the "blues rock" lead guitar genre. In 1979, music historian Richard T. Pinnell called 1963's "Memphis" a "milestone of early rock guitar". In 1980, the editors of Guitar World magazine ranked "Memphis" first among rock's top five "landmark" guitar recordings, ahead of recordings by Jimi Hendrix, Eric Clapton and Mike Bloomfield. Reportedly, the pitch-bending tremolo arm commonly found on electric guitars became known by the term "whammy bar" in recognition of Mack's aggressive manipulation of the device in 1963's "Wham!".
Mack brought a strong gospel sensibility to his vocals, and is considered one of the finer "blue-eyed soul" singers of his era. Crediting both Mack's vocals and his guitar solos, music critic Jimmy Guterman ranked Mack's first album, The Wham of that Memphis Man!, No. 16 in his book The 100 Best Rock 'n' Roll Records of All Time.
Mack released several singles in the 1950s and 1960s. Between 1963 and 1990, he released thirteen original albums spanning a variety of genres. He enjoyed his greatest recognition as a blues-rock singer-guitarist, with especially productive periods during the 1960s and the latter half of the 1980s. Mack switched musical genres and slowed or idled his career as a rock artist for lengthy periods, due to an aversion to notoriety, disenchantment with the music business and a preference for the simpler, less public, country lifestyle of his youth.
