What about Rockhouse Annie and the M&M Girls "Live At The First Street Alley"? I think that's one that often gets overlooked? But seriously how can you have never even HEARD of Toots & The Maytals?
Most overlooked LPs in the last 20 years
I thought this would be a good conversation starter. Try to keep the sonic aspect out of it, just a purely musical basis would be preferred. I'm going to limit my choice to (one) right now which I'm currently listening to, The Pretenders "Last of the Independents".
