Wynton made five albums for Verve. The first two, "Comin' in the back door" and "It's all right" are the ones you're thinking of. There's not much in them, really, though the latter has a moment or two with steel drums. The last two - "Smoking at the Half Note" and "Willow weep for me" were both drawn from his 1965 live session with Wes, though the second has strings overdubbed. (I think there's an undubbed version of this somewhere.)
In the middle, there's one called "Undiluted" which I heard once but haven't got. I saw it was scheduled to be reissued two or three years ago, but it never came out, to my knowledge. Now, from what I remember from hearing it over 40 years ago, THAT was a truly ACE session. With Paul Chambers & Jimmy Cobb (Ray Stevenson on flute on one cut).
And then he did "Full view" for Milestone, in 1966, another straight ahead trio session, with Cobb & ROn McClure. I like this one very much indeed.
So I don't think he sold out so much as got temporarily caught up in Creed Taylor's wish to make smooth jazz records that hit the charts.
