It is a title that sells when the media isn't great but the cover's ok, for sure
Normally I gravitate towards the groovy or lysergic 60s/70s gear in this category, but Les is just quality.
You're not skipping tracks on 'Tamboo!', the Theremin showcase 'Music Out Of the Moon' from 1947 is ok, and 1969's 'African Blue' got the plain green jacket of quality when it became KPM1070 in the 1000 series in the UK.
He's one of my favourite artists for sure, wish I'd bought some of it when it was cheaper.
