In 1991, Greenwood was three weeks into a degree in music and psychology at Oxford Polytechnic when On a Friday signed a recording contract with EMI. He dropped out of university and On a Friday changed their name to Radiohead. The band found early success with their 1992 single "Creep". According to "Rolling Stone", "It was Greenwood's gnashing noise blasts that marked Radiohead as more than just another mopey band ... an early indicator of his crucial role in pushing his band forward." Greenwood wrote his first Radiohead string part for the middle eight of "My Iron Lung", which appeared on their second album, "The Bends" (1995). Radiohead's third album, "OK Computer" (1997), achieved acclaim, showcasing Greenwood's lead guitar work on songs such as "Paranoid Android". For the track "Climbing up the Walls", Greenwood wrote a part for 16 stringed instruments playing quarter tones apart, inspired by the Polish composer Krzysztof Penderecki.
