Watch the Can Ya Dig It? online guitar lesson by Brad Carlton from Chord Studies: Jazz Funk Vol. 1
This lesson will give you a very valuable principle for creating interesting voicings from the stock voicings you might already know. The first chord, D7#9 is of course the famous "Hendrix chord", which is a staple funk chord which you may know. We have a natural third in the chord as well as the #9, which is the same as #2 or b3. For the second chord here I swap these two voicings to get a "sideways" sounding change that works great for jazz funk.
