Music feature: Peter Gabriel's "So"

It's time for our Tuesday Music feature and today we're celebrating the 40th anniversary of Peter Gabriel's seminal 1986 album, 'So'. After leaving his band Genesis, Peter Gabriel struggled to truly cut through as a solo artist. By 1986 he had released four self-titled solo albums, but despite a few charting singles, he was not what you'd call a "pop star". However, that all changed with the 1986 release of 'So', and music journalist Simon Sweetman is here to tell us why.
