I'll go with the 60s, which is much more challenging for me because there's a black hole of free jazz and samba before 1965. Of course this list wouldn't make any sense with six Dylan records or five Rolling Stones albums, so each artist appears only once.
1960
Miles Davis - Sketches of Spain
John Coltrane - Giant Steps
Eden Ahbez - Eden's Island: The Music of an Enchanted Isle
1961
The Ornette Coleman Double Quartet - Free Jazz

Max Roach - We Insist! Max Roach's Freedom Now Suite
1962
Bill Evans Trio - Waltz for Debby
Sonny Rollins - The Bridge
Stan Getz & Charlie Byrd - Jazz Samba
1963
Mingus - The Black Saint and the Sinner Lady
Jorge Ben - Samba Esquema Novo
Prince Buster - I Feel the Spirit
1964

Monks - Black Monk Time
1967
Love - Forever Changes
The Jimi Hendrix Experience - Axis: Bold as Love
The Beatles - Sgt. Pepper's Lonely Hearts Club Band
1968

Blue Cheer - Vincebus Eruptum

the amount of stuff I was forced to leave out of this list (especially 66-69) is astonishing.
