Here is a lttle project I am working on at the moment.
and this is a tweked mix with higher rhythm section levels:
The rhythm section (Piano, Bass & Drums) is JABB but everything else is "real".
The crucial question is - "Does the rhythm section sit nicely with everything else, or does it sound artificial".
The chart is a Neil Hefti composition/arrangement for the Count Basie Band. The "real" instrument recordings are pretty much a first take with the odd slip and fumble - the purposes being to see if the real/sample mix works as music and doesn't sound artificial.
Thanks for listening - and please be critical - if it sounds rubbish, I need to know.
