Michael Brecker is one of the best known jazz sax players around today, he's recorded a lot with famous pop stars, and is known for having kind of a lead guitar sensibility to his playing --also, he is much influenced by John Coltrane, so, as I said, he's a bit edgy.

One of the things that he does, and it is probably what you're hearing, is that he plays arpeggios over a chord that are not based on that chord, The trick to this is is that, though they aren't explicitly the chord, the "out there" arpeggios will extend from one of the notes in the chord that is being played.

An example of some thing that he might do would be   to play Dm7, Gm7, and Abmaj7 arpeggios over an F7 chord (not in this particular tune)--

There are reasons that you would do that--often, you get there by simply building vertical chords above the notes in a melodic passage.
