It's been a while since we posted an off-topic Sunday, but here goes. This is a good one.
I heard this song, Cavern by Liquid Liquid, for the first time very recently and it blew my mind when I realised what it was. Obviously it's instantly recognisable as an art school funk take on Grandmaster Flash and Melle Mel's seminal hip-hop song White Lines. Except it isn't. This song predates White Lines, and the band, Liquid Liquid won a court battle for compensation as it was sampled (that seems too small a word for the wholesale thievery) without permission.
Unfortunately for Liquid Liquid, and their record company, they didn't get a bean. The groundbreaking hip-hop record label that released White Lines, Sugar Hill, went bankrupt before paying up.
