You know what, Oasis is one of my hidden faves too. It reminds me about the first time i listened to "Incognito".

It has a very good groove and the lyricon solo give it a very distinctive sound and personality.

I know what you mean, Eril.
Oasis would have been my early favorite from that album, if not for that thing called Old San Juan. (It took a while for Incognito to overtake those two, and What Exit and Harbor Nights aren't far behind in the 4 and 5 spots.)

What happened to mwe with Incognito(the whole album) was that i got crazy with Old San Juan.....Duhhhh!! , Last Exit and Incognito. For a 10 year old who's starting to study the piano it's amazing to listen to such a complex variety of songs. Then one day i was just fooling arround with the piano and Oasis came in to my mind.

Last Exit is a cool song to begin with, but I came to like it even more when I heard it during the commercial break of a TV show.
I was in Los Angeles when a friend and I got passes to view a taping of the Merv Griffin show. His guests that day were Jaclyn Smith (one of the original Charlie's Angels), Carl Lewis and I can't remember the third guest, but it was a singer.
For anyone who's never been to a show like this, they record it in real time. That is, they start promptly on the hour, play the theme song, the whole works. So when they cut to a commercial, the music is piped in, and the host will chit-chat with whatever guest is on stage at that time, and the "on the air" lights will be off for the entire 2 minutes (or however long the break is), then they return to the show. So if it's an hour-long show, you're actually in the studio for the entire hour.
Anyway, it was during one of these breaks that I heard Jay's sax:
ba-de-da-bah BAH-bah-ba, ba-de-da-bah BA-da-DA ba-da-da-be-dahhhhhhhhhh
I recognized it right away as "the opening song from Incognito" but couldn't think of the title. (This was just before Christmas in 1985.)
And, of course, they continued to play the song through the break.

This is not really a "hidden" favorite, but since it's on In Modern Times, there's so much competition, it doesn't get the notice it deserves:
East River Blue
It's a cool song to begin with. But Jay's sax and Schuu's extended solo put this one in a class by itself.

Hard to believe this thread hasn't been touched in so long.
Anyways, each time I hear Early Light from Stories Without Words, I like it that much more. Julio's solo is one of his most dramatic.

Three long forgotten tunes that just rocks:
Canaval - well, this is just what's it's all about
Freetime - awesome arrangement
Latin Streets - Chet's solo blows away

but on the other hand, it's hard to pick any tune as they are almost all outstanding
