You'll need to go to iPlayer (it's not available on You Tube), and navigate 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.The story is of an older man, who was damaged by psychedelic drugs in the 1960s, reliving his experiences through more such drugs, and the music is background to his 'trip'
Any info on the track (if indeed it was one), band (ditto), or suggestions for sources of similar music gratefully received. Shazam has not been my friend.
TIA!
