I bought two of the Melles, the Quintet/Sextet, and the Volume 2, and Howard McGhee's Vol.2 at Tower Records on East 4th Street, in the main Jazz section's record nook. Even in the late 1990s-early 2000s they continued to carry albums, not many, but enough to fill an approximately 8 foot-long rack. They had a lot of cheap OJC vinyl, European free jazz titles, and some expensive Japanese reissues. Next to it was the jazz-related book and magazine section, where they sold the Swing Journal, among other publications. I have three issues of that magazine that I got from there, just for the pictures.
Tower had these 10" Toshiba-EMI Blue Notes priced at $28.99-$29.99, and they had maybe 10 titles. My records from the series have price stickers on the shrink wrap.
