One of the best jazz groups of all time. No question. Different people prefer different eras (early Miroslav albums, mid-decade Alphonso Johnson, the Jaco years, and the 80s stuff) but there are gems throughout their discorgraphy. My favorite tracks:

-Cucumber Slumber (with an insane bass line from Alphonso Johnson)
-Freezing Fire (live)
-Black Market, Cannonball, Elegant People, Barbary Coast, Herandnu
-Birdland, Teen Town, Harlequin, Palladium, Havona
-River People, Young and Fine, Punk Jazz
-Port of Entry, Rockin in Rhythm, Three Views of a Secret (though I prefer the version on Jaco's Word of Mouth album)
- Volcano for Hire, NYC Part One
- This is This
