First Concept Album?

[Recky]

Journey to the centre of the earth was the first 'concept" album i purchased, i must say after listening to kiss and akkadakka , Rick blew my mind with his chops

According to Wiki the very first concept album is Woody Guthrie's Dust Bowl Ballads
.

I have that album, I've never thought of it as a "Concept Album", but now that it's been mentioned I guess it is, sort of telling the story of the dust bowl & great depression. Released in 1940 it would have to be one of the first.
