Quite a facinating album addressing the intersection of jazz and religion. The concept of this is definitely novel and the musician lineup is top notch, but the result has some odd quirks.
Tracks "Torah Service/Adoration" and "Final Amen" (8 & 9) are the main "prayers" with the rabbi doing some preaching sounding like spoken word over a jazz vamp. The rest of the tracks are a mix of arranged vocal melodies and solid modal jazz. Sometimes they compliment each other, but the balance is constantly being shifted. If you're looking for quality jazz (especially Herbie), there's some really fun playing! His comping is swinging and crisp, and the solos are all quite tasteful and fresh.
If you're looking for lots of spiritual singing, be warned that there's many long instrumental solos and interludes. In addition, the arrangements for the 2 singers can get quite dissonant and distracting. I guess the composition is a great feat for a 17-year old composer (who also plays french horn admirably on the album), but the resulting vocals seem to have focused on complexity over melody.
Mixes of religious jazz can be intriguing, but but for those looking for more jazz and slightly tamer and accessible Jewish content, my favorite novelty recommendation is Cannonball Adderly's stellar Fiddler on the Roof, a hidden gem! Of course, if you want spiritual jazz and don't own it yet,A Love Supreme is mandatory.
