Paul Daniel "Ace" Frehley is an American musician who was the original lead guitarist, occasional lead vocalist and founding member of the rock band Kiss. He invented the persona of The Spaceman and played with the group from its inception in 1973 until his departure in 1982. After leaving Kiss, Frehley formed his own band named Frehley's Comet and released two albums with the group. He subsequently embarked on a solo career, which was put on hold when he rejoined Kiss in 1996 for a highly successful reunion tour.

Kiss was an American rock band formed in New York City in 1973 by Paul Stanley, Gene Simmons, Ace Frehley, and Peter Criss. Known for their face paint and stage outfits, the group rose to prominence in the mid-1970s with shock rock-style live performances which featured fire-breathing, blood-spitting, smoking guitars, shooting rockets, levitating drum kits, and pyrotechnics. The band went through several lineup changes, with Stanley and Simmons remaining the only consistent members. The final lineup consisted of them, Tommy Thayer, and Eric Singer.
