Chuck - do you mean all of Herbie's 70's output or just the funky Headhunters and onwards stuff?
There is a world of difference between the Mwandishi band material (71-73) and the later albums. Not so much funk - but more a serious and highly evolved usage of electronics combined with world percussion and pretty avant-garde jazz.
Its a unique period - documented on other albums such as Eddie Henderson's 'Realization' and 'Inside Out' sessions for Capricorn, Julien Priester's ECM album 'Love Love', Bennie Maupin's ECM album 'Jewel and the Lotus' and Norman Connors first 3 albums for Cobblestone.
Very far removed from the fusion-funk of the mid-70's - this is ethereal stuff - a heady mixture of free-jazz, afro-centrism, new electronic musical technology and recording techniques.
The whole Mwandishi vibe lasted just 2 years - the reasons for Herbie abandoning it are told in his sleevenotes to the recent Headhunters CD remaster.

You did not mention a single piece of music in my collection. Sorry.
PS: I have heard all this stuff - got promos of most of it and gave it away. Not proud, just factual.
