Query: Brilliant Performance!

While the sound quality may not be the best the performance more than compensates for any technical flaws. Why would you expect any different from a recording made in the '50s?!! With a little tweaking from a equalizer or fade down in the treble on your amp you find much ear pleasing sounds in this very important historical performance! Collectors of these types of recordings are used to the sound of this era and some even prefer it above the glitzy and over produced recordings of the present day.
