This is some of the most important music of my high school years. In 1972-3, I was playing rhythm guitar in the legendary band, Captain Gridzork and His Magic Aardvark Band. On one song, I played violin (to my shame) on Locomotive Breath. Hymn 43 and My God are thought-provoking, at least for a young preacher-to-be. I saw Tull in Roanoke, VA in 1973, touring behind Minstrel in the Gallery. The music video broke and they wound up playing just about all of Aqualung and Thick as a Brick…
Where to begin with John McLaughlin? He played guitar with Miles Davis (who named a song for him on Bitches Brew), then helped define jazz-rock fusion with his Mahavishnu Orchestra (saw them in Lowell, MA in 1973). His guitar playing is fast and accurate and creative. He made a very interesting album with, of all people, Carlos Santana (another spectacular guitarist). Then came Shakti, a jazz/rock/Indian fusion group. Nobody sounds like them. The man is a force of nature.
The Best of Andrés Segovia: The Millennium Collection
For a man who did his very best playing back in the 1920s, at the dawn of modern recording, he was still astounding when I saw him in the late 1980s (if I recall correctly). Even when he was almost 90 years old, and with fingers like sausages, this man WAS the music. He made some very minor technical/mechanical errors, which I'd noticed because I was studying some of the pieces, but none of that mattered. At all. He just about created what we know as "classical guitar" today. Glorious.
