R f sayles,
HMMMM- My guess is that these LP's were all issued in the early 80's, perhaps in the same year?

Tonight, so far:
"Il Cornetto, Works Of Italian and British Composers of the 16th & 17th Century" (Klimo Edition Open Window OW 004)
Baroque era music performed on original instruments including the cornett, viola da gamba, harpsichord/chamber organ and lute/baroque guitar.

Liszt "Sonata, Piano Works By Franz Liszt" Robert Silverman
(Stereophile STPH008-1)

R f,
I have to append my answer: They weren't all issued in the same year, or in the early 80's. I didn't take into account "Beggar's Banquet" and a couple of others. My other guess would have been that each LP was the second effort for each artist, but the Led Zep is their 1st LP, right? I give up. What is it?

A very entertaining Impulse! 3-LP set called The Saxophone, A Critcal Guide. Don Byas is playing All The Things You Are right now. Great stuff.

A clue is: they contain one key player in all of these recordings....
