A little while ago I asked for help from the group in identifying the
track/band/genre of a piece of music played as background to a scene in
the TV series Waking The Dead, to which you kindly replied with your
thoughts.

Since then, I've been doing some research, namely listening to the
results of a search for 'psychedelic rock' on Spotify.

An early candidate for the formative piece in question was Jefferson
Airplane's Won't You Try/Saturday Afternoon from their 1969 album The
Woodstock Experience, in which the bass line of the 'middle eight' might
have been the inspiration for the piece from the TV series. At 2m45 into
the track there's a change to a slow tempo with chord structure and bass
line suggestive of that from the TV series.

However....I've just stumbled across Mind Flowers from the group
Ultimate Spinach and their 1968 album Behold And See. The whole track,
some 9m40 long, is slow psychedelic rock and which is very reminiscent
of the relevant part of the background piece from the TV series, and
could well have been the source of inspiration for it. Interestingly,
the track concerns someone with a troubled mind, exactly the same as
that part of the Waking The Dead episode the music is background to. You
tube video he

[Navigate on iPlayer to Series 6 of 'Waking the Dead', Episode 9
("Double Bind" part 1). The incidental music of interest occurs in two
places, 35m32 to 36m02, and a longer piece at 38m35 to 39m53]

See what you think.
