you have to download, buy, beg, borrow or steal a copy of his "So" album that Mercy Street comes off. Get acquainted with it and allow it to creep up on you till you realise you have been listening to something special.
"The success of the album earned Peter Gabriel two awards at the Brit Awards in 1987: Best British Male Solo Artist and Best British Video for "Sledgehammer". The album also received four Grammy Award nominations: Best Male Rock Vocal Performance, Song of the Year, Record of the Year (all for "Sledgehammer"), and Album of the Year." http://en.wikipedia.org/wiki/So_(album
