John Oswald's 1989 CD Plunderphonics spawned a new category of music which samples not just pop songs, but their cultural contexts as well. Since then Oswald has refined his "electroquoting" on the CDs Greyfolded, Electrax, Discosphere, Plexure and the recently released Plunderphonics box set. In his Radio Radio program he talks about the legal machinations that have surrounded his work and plays a range of examples.
