Ahh, acid jazz, groovy, nocturnal, slick, sampled, jazz. Down to the Bone is one of my favorite groups from the genre, they combine excellent catchy rhythm samples with live instruments as guitar, keyboards, bass and sax as a whole making a funk fest of the highest caliber.
Their debut, From Manhattan to Staten (1997), has a way more electronic feel rather than real band one, but that's where the majesty lies on. It even tends to be more soft jazzy compared to the more funk-oriented Jamiroquai, also Down to the Bone here is completely instrumental.
What you will find in this music is rather common grooves from either soul jazz or 70s funk-jazz filtered with the modern sampling devices and keyboards, and extended with catchy soloing.
If you're into groovy music, this is a must-have. Probably not the most innovative acid jazz album out there, but a highly enjoyable one nonetheless and a classic in my opinion.
