I've had a copy of his 'All What Jazz' book for many years. It's a compendium of reviews for UK jazz releases from 1961 to 1971 that were originally published in the Daily Telegraph and a pretty good reference for UK LP releases of that era (he gets to review some real obscurities). Anything beyond the swing era tends to floor him (particularly Coltrane) but he writes with real insight. It's also very funny in parts.
A typical sample:
'Albert Ayler's 'New Grass' (Impulse) is an extraordinary piece of-work, being (not to put too fine a point on it) a rock record by the master of the gothic galosh. The first track 'Message From Albert' has the usual screeching, plus some half-baked nonsense about having lived before, but after that it is all soul, Gospel, R&B and even Lat-Am, giving the reader the worst of both free form and funky worlds.'
