PPK was a famous Russian trance duo that was based primarily in Rostov-on-Don. The group consisted of Sergei Pimenov and Alexander Polyakov. PPK name is the acronym of founding members' initials, K was for short-time member DJ Kordj (Roman Korzhov).

PPK became popular abroad due to their single "ResuRection", which was available to download for free on mp3.com for about a year. A few million people downloaded it and a such wave of popularity brought to signing a contract with Paul Oakenfold's Perfecto label and was used to celebrate the New Year 2003 in Warsaw, Poland (seen on Sky News Active, 2002-12-31).

"ResuRection" was based around the melody of the theme of Latvian electronic rock band Zodiaks to the 1979 Russian (Soviet) film Siberiade by Eduard Artemyev and contained, in some remix versions, vocal samples of Cosmonaut Yuri Gagarin.

The group broke up in 2004, however Pimenov did remixes for the group t.A.T.u.'s single "Lyudi Invalidy" under the name PPK.
