Roots of Ningen Isu

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 that featured fire-breathing, blood-spitting, smoking guitars, shooting rockets, levitating drum kits and pyrotechnics. The band went through several lineup changes, starting with drummer Eric Carr replacing original drummer Peter Criss in 1980, with Stanley and Simmons remaining the only consistent members. The final lineup consisted of Stanley, Simmons, Tommy Thayer and Eric Singer.

UFO were an English rock band formed in London in 1968. They became a transitional group between early hard rock and heavy metal and the new wave of British heavy metal (NWOBHM). The band's final line-up consisted of vocalist Phil Mogg, lead guitarist Vinnie Moore, rhythm guitarist and keyboardist Neil Carter, bass guitarist Rob De Luca, and drummer Andy Parker. They had gone through several line-up changes, leaving Mogg as the only constant member, and had disbanded three times. The band's "classic" line-up comprised Mogg, Parker, bassist Pete Way, keyboardist Paul Raymond, and former Scorpions guitarist Michael Schenker. In May 2018, Mogg announced that he would retire from UFO after one last tour as a member of the band in 2019; however, their farewell tour was set to conclude in 2022 before it was cancelled, due to Mogg's health issues. Mogg confirmed UFO's third disbandment in April 2024.
