My gateway to UK psych was definitely Vernon Joynson’s Tapestry of Delights which I still consider a Holy Text. I like Galactic Ramble fine, but a lot of the reviews are for “rare” albums, aimed a bit at people who are looking for obscure records. while Tapestry of Delights made me aware of the regular bands that just never got attention over the pond in the USA.
It did so much better at band discography than Rolling Stone Record Guide or even Trouser Press guides. Suddenly I could read about relatively unsuccessful albums by major bands (like Mott the Hoople’s “Wildlife” or “Mad Shadows” which were more rumors for me than albums when I was a youngster). Yup, Tapestry of Delights is still my favorite music guide of all time!
