Blue Note Tone Poet Series

Yes you are right. A big percentage of Tone Poet and Blue Note Classic series LP are curved.  The quality control should be better.

I only have the Blue Train and it is not warped. It’s also a very good sounding record. 

Wow, I've got at least two dozen of these purchased either at the local record store or through Elusive Disc and everyone is perfect. Flat, clean, low noise. These are some of the best jazz reissues out there IMHO.
