the other review (may be five stars - so they got that right) but sells Sander's spiritual blast that is "Black Unity " (from 1971)- very short. i got lucky with this having hired it from the London Barbican library back in '99 and was already under the spell of John Coltrane's broadly similar spiritual 60's free/modal jazz also on the Impulse records imprint.
"Black Unity" is an incredibly powerful and intense ensemble single movement thats builds in intensity with what might be compared to a combined horn ensmble sound to bring the walls of Jerico down style of biblical proportions. the recording combines the usual jazz ensemble ans also combined african instrumentation, and builds + builds upon a simple motif in intensity. "Black Unity" release is only 37 minutes long (in a similar vein and intensity to Ornette Coleman's "free jazz" LP + has similar large ensemble semi-free jazz intensity of John Coltrane's Ascension also), but is worth every penny as it features some fine fiery Sanders sax playing+ is a angry, spiritual,and intense blast of REAL jazz, not dinner jazz lite thats for sure...
In addition to the more typical jazz line-up and along with other personal favourites - yes, the widely acknowldged classic from Coltrane "A Love Supreme" from '65,"Africa/Brass" (from '61) and John's wife Alice Coltrane's "Ptah, the El Dhaoud" from 1970 (see my review also )and all on Impulse by the way - ALL amazed me and moved me, to learn of the "righteous" sound from across the atlantic.
INDESPENSIBLE "fire music".
