The most important article to read is:
The Legend of the West Coast Pop Art Experimental Band.
This is the most exhaustive publication on the WCPAEB ever, first published in Ptolemaic Terrascope issue 26 and 27, Feb./July 1999.

For an one-hour interview with Tim, talking about the WCPAEB see YouTube.

The album The Smoke made in 1968 (Sidewalk 5912) by Michael Lloyd after his (initial) departure from the WCPAEB, will probably be reissued. It's broadly in the mood of other LA studio-psych albums of the period. An album of mild psychedelia it contained a fair degree of orchestration and was probably influenced by The Beatles Sergeant Pepper, released the previous summer. Some tracks like 'Fogbound' and 'Umbrella' had considerable commercial potential, others like 'Song Thru Perception' are notable for their crispy clear vocals and 'October Country' for some beautiful string arrangements. Hold for release details....

While still possible, get your WCPAEB T-shirt from this Spanish site ShopMania. Very unique, and available in many colours too.

Last year the Californian magazine Great God Pan also published a fine feature about the West Coast Pop Art Experimental Band, written by Erik R. Bluhm (thanks Erik!).

The Yardbirds-biography (by John Platt, Chris Dreja and Jim McCarty, 1983) includes a chapter describing a party at Bob Markley's House during their first US tour in 1965.
Here an excerpt of this chapter.

Also visit the The Electric Prunes site. It includes an interview with Bob Morgan, the brother of Ron Morgan, who played lead guitar on the three WCPAEB-Reprise albums.

Jimmy Greenspoon, the longtime keyboardist for Three Dog Night, played in an early version of WCPAEB, and talks a bit about it in his autobiography "One is the loneliest number". He was boyhood friends with Michael Lloyd, thus his connection. (Apparently, Michael Lloyd is the source for the tapes that is used for the Sundazed CD, as he was the only one who cared enough to hold on to them!) In the '70's, there was a mini-WCPAEB reunion in a very unlikely place: Shaun Cassidy was being produced by Lloyd, and had Shaun Harris and Greenspoon in Cassidy's band!

Other WCPAEB related recordings:

Outta'Town / Outer Space - Earworm records - Worm 71.
A mini tribute-album (March 2003, 10" vinyl, 6 tracks) featuring 3 British and 3 Canadian bands: Lucky Luke ("Will You Walk With Me"), The Smoke Rings ("Smell Of Incense"), The Transparant Fan ("I Won't Hurt You"), The Orange Alabaster Mushroom ("Until the Poorest People Have Money to Spend"), The Clientele ("Tracy Had A Hard Day Sunday") and Southall Riot ("High Coin").

Lucifer & The Peppermints - Green Itch Got The Bear / Money Back Guarantee (RHM 45-1001 196?).
Both sides are written by Markley and the A-side is a (totally demented) song about a bear that loses its hair, sung in Markley's 'A Child's Guide'-style voice (as in "Come with me through the forest", etc). From the style one would place it at the beginning of the decade. The flip is a re-write of Summer's Comin On.

Trey Barker - Valley Of Tears, Part 1 / Valley Of Tears Part 2 (Fifo FB-101 196?).
Both sides credited to Knight / Markley, one side instrumental (with a guitar solo which is so bad it may have been 'played' by Bob Markley himself) and the other with a vocal which, despite sounding a little like Markley, is so well sung it has to be by somebody else.

Goodness And Mercy - Goodness And Mercy (LP on MGM SE 4730 19??).
Produced 'live in the studio' by Markley. The record is basically brass / rock), but three tracks are of interest: Dirty Anne is written by Markley and other members of the group, and Thousand Pound Woman and Circus Man are co-written with Dan Harris. Both are classic Amos-era songs (especially the last).

Every song in this album has been written, arranged, sung
and played by the group. No one censored us. We got to say
everything we wanted to say, in the way we wanted to say it.
Bob Markley.
