So.... if I were the OP and wanted a few reference recordings on vinyl to acquire and evaluate vinyl playback systems, what would you recommend?
They must be available (re-issues or original pressings that don't cost an arm and a leg), sonically excellent and not boring musically. They must show off what vinylphiles
prefer about analog - emotion, "meat on the bones", "flow", etc. Please note that this is NOT intended to denigrate digital in any way. In fact, some of my favorite LPs were recorded in digital.
Here are my suggestions:
Jazz - Swiss Movement: Les McCann and Eddie Harris. This was the result of a spontaneous pairing during the Montreux Jazz Festival 1969. I think that it's one of the most exciting and exhilarating jazz performances ever captured. The musicians have tremendous fun and this comes across in spades on the opening track "Compared to What".
Big Band - Les Brown and his Band of Renown Goes Direct to Disk. This is probably the most easily available Direct to Disk album in existence that is any good. Every track is excellent, fun, and hugely dynamic (almost as good as the extremely expensive M&K 'For Duke').
Modern Electronica - Yello: Touch Yello. An album I've demo'ed at almost every show in the past 3 years. It was originally released only on CD, but a 2-LP album was released in Europe in 2010 which was (in my preference) much better. The first track 'The Expert' is the definitive test for bass definition - one that does not (in my system) show as well on the CD. However, a high-rez rip of the album does it for me (in my system).
Female Vocals (audiophile music) - Rickie Lee Jones: Girl at her Volcano. There are various excellent re-issues from the talented Ms Jones, but I think that 'Under the Boardwalk' (Side 2 Track 1) is one of the best examples of her craft (and not over-played unlike her first album and "Pop Pop").
I'll stop here and see what others recommend
