Thanks for the detailed reply. I have listened more to the Tjader album mainly because I have it on CD, whereas the Shearing I have only on LP. I just remembered liking the woodwind arrangements on both, and then finding out they were both Clare Fischer, and from the same period. I should spend more time with the Shearing album - with or without a cocktail - to get a better idea of the contrast.
Did you listen to Tjader track 4, and exotica track, and do you like that one?
