Well, it shouldn't be jazz all the time. Rock music has brought some marvels too. Here are my favorite albums.
Jimi Hendrix - Blues
(I'm sorry guys, but this "Here My Train A'coming" is beyond belief - I do not think that any musician went deeper into the essence of the blues than Jimi), but all of his other official albums should figure here as well.
Hendrix is on the same level as Bach, Beethoven and Coltrane.
The Allman Brothers Band - Live At The Fillmore East
This is possibly the best rock live album ever, next to the Rolling Stones "Get Yer Ya Ya's Out" and the "J. Geils Band Live". But also listen to Goin' Down Slow on the Duane Allman Anthology 1 to get an idea about Duane's absolute mastership : less is more : how a few notes can tell it all : the sign of a true master.
King Crimson - The Court Of The Crimson King and Red (including the phenomenal "Starless")
I should also not forget.
Frank Zappa : Hot Rats
The Soft Machine : Third
Gong : You
The mad French-British space-rock band brought something unique and unparallelled in music history.
