A Sheffield music star has hidden copies of his albums across Sheffield for members of the public to find and listen to.
Violinist and singer Matt Howden, best known for his work under the name Sieben, has scattered the records across Sheffield as well as in Barnsley and the Polish city of Wroclaw.
He wrote on Facebook: "Enjoying my own lo-fi version of Pokémon Go - leaving Sieben albums out in public for the sharp-eyed to find.
"Current locations: underpasses, bus stations, pubs,showrooms, substations, and shop fronts in Sheffield, Barnsley, and Wroclaw."
The musician has released a number of albums since beginning the project in 1997.
