Mark Murphy - cd/sd

so i've recently been picking up his early/mid 70s Muse records and have been totally into them. i've got Mark 2 and Bridging the Gap so far. they're both mellow vocal jazz with nice electric piano. kinda remind me of a brian auger & julie driscoll record i have, but with a lot better voice, and a little less fusion-y. for a long time i thought he was what i wished Steely Dan would sound like if i liked them, but all of a sudden i love them, so now he just sounds like a looser version of them. the opening line of the first song on Mark 2 sounds exactly like the way david grubbs would sing something on some gastr del sol stuff.

so anyways, what's good? what's bad? is his earlier work interesting? i mean he's been around since the mid 50s and it looks like he's still putting out albums (geez, are those comps?)
