Have a read about this great project which raised a substantial amount of money for 
Shelter Scotland!
“The project was conceived by Shona Brown who set up and runs both SoundRoutes and the prison choir. Shona is an award-winning flautist and singer-songwriter. ‘Changing Key’ is a four-track EP featuring prisoners from Addiewell Prison, West Lothian, and members of SoundRoutes Singers choirs from Central Scotland.
Recorded and released in 2012, the project raised over £3,000 for the charity Shelter Scotland and is available online from iTunes, Amazon and CD Baby. The four-track EP includes Primal Scream’s Movin’ On Up and Behind Blue Eyes by The Who, featuring a solo by one of the prisoners.” – Andy Hurst, Soundroutes
