We love these isolated bass tracks. While not so isolated, you can really hear Ray Brown‘s bass on this reworked version of the James Brown hit, “Papa’s Got a Brand New Bag”, with Louis Bellson’s orchestra. Lots of leakage on this recording, because the bass was mic’d, while the band performed live.
The first part of this video is the bass isolation segment. The second half is the band and vocals (without Bellson’s drum track).
