The John Lydon-fronted band release the four-track One Drop EP on April 21 to mark this year's Record Store Day.
Comeback album This Is PiL follows on May 28. It was recorded last year at Steve Winwood's Cotswolds studio and will be released via the band's own PiL Official label.
Lydon said: "'One Drop' is a reflection of where I grew up in Finsbury Park, London. The area that shaped me, and influenced me culturally and musically, a place I will forever feel connected to.
"But within this I am also saying it doesn't matter where you come from, we all go through the same emotions especially the disenchanted youth of today, yesterday and the future."
He added: "Bearing in mind the Olympics are in London this year and who knows what that could bring for London and our country."
The full One Drop EP tracklisting is as follows:
1. 'One Drop'
2. 'I Must Be Dreaming'
3. 'The Room I Am In'
4. 'Lollipop Opera'
PiL were recently confirmed to perform live at the BBC 6 Music ten-year birthday celebrations on March 16 at London's Queen Elizabeth Hall.
The band will also play the Brighton Concorde on August 15 and 16.
The current Public Image Ltd lineup features Lydon together with ex-Damned guitarist Lu Edmunds, former Pop Group drummer Bruce Smith and Spice Girls reunion tour musician Scott Firth.
