Jerry Mulligan - Dragon Fly - track two - Brother Blues
Tom Scott - Smokin Section - track 5 - Ode to Billie Joe (yes that song)
Miles Davis - In a Silent Way - Side 1
Al Di Meola - The Infinite Desire - Track 6 - Invention of The Monsters and Track 10 - Race With The Devil on Turkish Highway
These tracks will show everything a system has to offer. IMHO
