Vanity vinyl: The era of homemade records
15 August 2013 Last updated at 00:01 BST
Record collectors usually go in search of rare and valuable copies of albums by iconic artists. But Johan Kugelberg has instead unearthed a collection of vinyl treats by musicians who probably never sold a single copy.
The book Enjoy the Experience, edited by Kugelberg along with Michael P Daley and Paul Major, chronicles the rise and fall of the homemade record, from the 1950s to the early 1990s.
He talked to the BBC about the music - and the art work - created by Americans who may never have made it big - but who at least made a record.
