Back to David Diggs with Out on a Limb from 1976

Information is here. Note Diggs is playing drums, guitars, and keys on this release. Actually when he ditched the big band, the arrangements got better, more in the fusiony direction which makes sense given how hugely popular it became in the mid-70s (big sigh)... 

The string arrangements which appear here and there are not synthesized, but an actual string section arranged by Diggs himself, and it's nice to hear those too. 

Music consists of instrumental smooth fusion throughout, some lovely hooks and melodies usually played by his George Benson-style electric guitar, note some songs are repeated from earlier and from his later albums-- which is OK, as those tend to be the better compositions.  One that only appears here, though, is the Seventh Seal:

Instant Joy is such a lovely and marvelous composition, albeit simple.
