Fair enough.
That said, I wouldn't describe the album as "groove oriented." To my ears, rather than rock, it's Boland's compositions that increasingly rely on 20th c. "classical" techniques that sets the album apart.
You hear more of the same on the Getz record, A Change of Scene.
My 2 cents.
EDIT
I'm listening to Off-Limits again. And, well, maybe some of the music is rock-ish and groove oriented. Point taken. In any case, I enjoy the music.
