Paul Daniel "Ace" Frehley (; born April 27, 1951) is an American musician and songwriter best known as the former lead guitarist and co-founding member of the rock band Kiss. He invented the persona of the "Spaceman" or "Space Ace" and played with the group from its inception in 1973 until his departure in 1982. After leaving Kiss, Frehley embarked on a solo career, which was put on hold when he rejoined Kiss in 1996 for a highly successful reunion tour.
Frehley's second tenure with Kiss lasted until 2002, when he left at the conclusion of what was originally purported to be the band's Farewell Tour. His most recent solo album, Origins, Vol. 1, was released on April 15, 2016. Guitar World magazine ranked him as the 14th Greatest Metal Guitarist of All Time. His solos often incorporate the minor pentatonic scale and the use of vibratos. Outside Kiss, Frehley had commercial success, with his first solo album going platinum. His first album with his "Frehley's Comet" band was also a big seller. Frehley is also known for the use of many "whimsical" guitars, including a Gibson Les Paul guitar that emits smoke from the neck humbucker pickup and produces spinning pyrotechnics, and a custom Les Paul that emits light based on song tempo.
