Why do some cd's have no bass

Now I'll be running my Squeezebox Touch in Spectrum Analyzer display mode to really see which CDs truly have no bass. most seem to have at least some as would be expected.

I'll assume solo recordings featuring Piccolo and Female Voice might get a free pass for having no bass?

Why do some recording artists have no musical talent but lots of bass?

I have noticed that artists who use an acoustic bass rather than an electric often have bass that is less prominent in the CD. This does not have to be the case. Artists like Alison Krauss and Ramsey Lewis have made the choice to use the acoustic option and many of their recordings sound very balanced. I actually prefer an acoustic bass for certain genres of music and appreciate the engineering skill necessary to get it right.

It's likely the fault of the person who mixed the multi-track recording down to two-track stereo. The liner notes should tell you who is to blame.
Mixing is an art and apparently there are successful professionals that don't "get it."

Compression or recording and mastering engineer's that do not know what they are doing.
