3. Lynyrd Skynyrd - Pronounced

6. Jimi Hendrix - Electric Ladyland
7. Bob Dylan - Blood On The Tracks

10. Kansas - Leftoverture
Good list although quite a few of these are actually from the 1970s - Lynyrd Skynyrd did not release their first album until 1973, for instance (awesome album though!). Something like Blood On The Tracks is slightly different as although it was released in the 1970s in that case Bob had been around since the early 1960s.
Led Zeppelin IIII (IV is the more usual numerical representation, you can also call it Zoso after Jimmy Page's symbol) was released in 1971, although for the 1960s you can have both I and II, released in 1969.
