No doubt you are right. I can’t help (whether consciously or unconsciously) but compare Brazilian Pop to the American music that’s far more familiar to me. I’m used to greater dynamic contrasts and variety of mood as opposed to the more understated, mellow MPB approach. Clube Da Esquina is not in this ultra mellow vein, however. The later "Milton" with H. Hancock and W. Shorter is good if not quite as timeless and and invigorating as Clube:

I like Flora Purim but the 70’s Fusion-tinged recordings that I’ve revisited now sound pretty dated to me, although I haven’t listened to all of them. Yesterday I was listening to some of Airto’s early solo recordings, some of which feature Flora’s vocals. I hadn’t heard those before and am interested enough to listen some more.

I will make a point of going through Flora’s recordings more comprehensively to see if there are some that might appeal to me that I’ve either forgotten or never heard.
