Even as the streaming revolution sweeps all before it, there are a few aspects of physical music that seem to be thriving: vinyl and the ‘historical discovery’.

Bass superstar Jaco is now a worthy recipient of both, courtesy of Truth, Liberty & Soul, a complete gig recorded at the Avery Fisher Hall in New York City on 27 June 1982, part of that summer’s Kool Jazz Festival.

The concert was originally broadcast live on NPR but has lain in the vaults for decades, and it took Resonance Records (via vaultmeister Zev Feldman) six years to prepare these tapes for release.

It features Jaco alongside his regular band (Bob Mintzer – saxes, Randy Brecker – trumpet, Don Alias – percussion, Othello Molineaux – steel drums, Peter Erskine – drums), plus special guest Toots Thielemans on harmonica and a big band full of NYC’s finest horn players.

The album catches Jaco at somewhat of a crossroads; by most accounts, June 1982 was the last time he was truly ‘together’ in terms of his mental wellbeing, the wheels really coming off during the Japanese tour later that autumn. (Fans of a certain age may fondly remember the televised live gig from the Montreal Jazz Festival which took place on 3 July 1982 – see below).

The question is, if you already own Jaco’s 1983 live album Invitation (released in slightly expanded form as Twins in Japan), also featuring the big band, is it worth getting this one? The answer is a resounding yes. It’s thrilling to hear a whole gig in real time by one of the last true jazz titans.

The sound is superb – crisp, deep and rich. The packaging is excellent, with a weighty booklet full of incisive essays and previously unseen photos. Anyone sick of bandleaders’ endless yakking to the audience to run down the clock these days will be pleased to hear that Jaco doesn’t utter a single word until a garbled band announcement during the closer ‘Fannie Mae’ – he’s there to play music.

There are many highlights – a killer ‘Donna Lee’, touching Afro-Cuban take on Toots’s ‘Bluesette’, an epic ‘Liberty City’ and particularly Mintzer’s superb composition ‘Mr Fonebone’, electrifying in big-band format.

There are one or two longeurs – we could probably do without the extended percussion and drum ‘improvisations’. And it has to be said that Jaco doesn’t sound on completely top form during his solos, though that’s possibly due to the size/acoustics of the venue, alluded to by a few contributors in the liner notes. But his accompaniment is typically brilliant throughout.

Frankly, it makes one desperate to attend such a gig in these crazy times. Truth, Liberty & Soul is a valuable release and an absolute must for anyone who owns any Jaco or Jaco-era Joni Mitchell/Weather Report albums.
