I posted 2 of his albums in the past, not so long ago back here. Style of music is that typical 1970s 'hard bop' with fusionoid accompaniment, that is, electric piano with angular horn section playing interesting long-winded riffs, etc. Typically the melody played by combined sax/trumpet in unison, advanced harmonies, not the usual circle of fifths jazz standard drivel.

The cool jazzy sound of Soft Spirit is just indescribable:
Another one, his Waltz for Boobuss which reminds me a lot of the slow and classic Miles Davis compositions like Little Church:
