Although the OP was about albums from 1971, it has drifted a bit into a 1960s vs 1970s discussion. In that regard, I find it a bit curious that one artist, who defined and redefined rock music has not been mentioned even once (although I might have missed it). He released in the 1960s more great music than all the other artists mentioned combined (in my opinion...admittedly very biased).
1963 The Freewheelin' Bob Dylan
1964 The Times They Are A-Changin'
1964 Another Side of Bob Dylan
1965 Bringing It All Back Home
1965 Highway 61 Revisited
1966 Blonde on Blonde
1967 John Wesley Harding
1969 Nashville Skyline
And he is STILL going strong. His new album (OK, "CD") is fantastic.
