About a decade ago I composed Mirage for my trio. I resurrected and updated it recently for a sextet I play with called Hexagon.
The melody, harmony, and vibe of Mirage come from what I refer to as the "Jewish Mode." (Some theory-savvy folk will think of this as the 5th mode of Harmonic Minor). Anyhow, the result is this Middle-Eastern-sounding thing that won't leave you alone, kind of like getting sand in your eye.
