What you find often depends on what you want to look for.
Shepp's a significantly more subtle and nuanced ballad player now than he was in the 60s. I love his 60s work as much as anybody (and perhaps more than many), but ballads of the type he plays on this album can't help but benefit from the broadened perspective of life experience (including learning more about the subtleties of playing melody and changes), and Shepp brings that increased life experience to the table as openly as he brought his political passions to the table in the 60s. If love, life, and money don't turn you around every now and then and make you reconsider some shit as time goes by, well, that ain't much of a life if you ask me.
So yeah, if you're looking for "angry" tenor or something like that, this stuff might well sound "blase". But if you're looking for soulful, nuanced, mature ballad playing that goes straight to the heart and speaks of and to a mature life, hey - it's definitely here.
As our Fearless Flyer implies, it's all good to me when it is in fact all good. And Blue Ballads is exactly that.
