A lot funkier and mellower - not so experimental. Electric piano from George Cables given prominence - advantageously so in my opinion. Bobby also plays a lot more on marimba I think than on his 60s classics.
Don't recall any (I'm going from the vinyl here as I don't actually have the Select).
Very low - in fact I wouldn't say any of it is painfully cheesy. Some of the albums (e.g. 'Waiting') have mellow, MOR-ish tracks but they are very tastefully done.
Like all of 'em - but have a particular fondness for 'Knucklebean', 'Cirrus' (some nice Woody Shaw) and the first side in particular of 'Waiting'. The 'Inner Glow' LP is real cool stuff too.
