Osymyso has been played on NTS shows including Night Shift w/ Diamondstein, with Pat n' Peg first played on 11 June 2015.

Osymyso (real name Mark Nicholson) is a musician and DJ from the United Kingdom who specializes in the genres bastard pop and breakbeat. He has been making music since 1994, but he released his first, album, Welcome to the Pailindrome, in 1999. His songs include Pat n Peg, which managed to turn an argument between two Eastenders characters into a beat through the looping of the shouts "You bitch!" and "You cow!", and Intro-Inspection, which brought the genre to its logical extreme. In a 2002 front page survey of the genre, The New York Times remarked on Intro-Inspection and called Osymyso "one of the most popular bootleg artists".

In 2005, Osymyso set himself the task of releasing one short track every week for 50 weeks, a project he called 05ymy50. However, progress was slower than hoped, and by year's end only 15 tracks had been completed. Despite this, Osymyso felt the project was at least a partial success: some of the tracks have been released on vinyl by Juno Records, and Osymyso has indicated that he may eventually finish the project, no matter how long it takes.
