Ed O'Brien on Jenny Eliscu

Ed O'Brien opens on his wish to capture Blue Morpho at 432 hertz, and then goes a very long way back, to listening to Simon and Garfunkel with his mother while she sewed, singing in a boys' choir, and the point where guitar music arrived and he lost his head over the Jam, the Police and the Smiths.

In the dark period the songs came from, his daily ritual was three hours alone in a small room playing guitar. He calls it therapy rather than writing, and it was only at the end that he realised he was holding a collection of motifs.

He pushes back on the available vocabulary. Mental health, he says, always feels an inadequate way of describing what anyone who has been in that place goes through, which he calls a crisis of the soul.

Near the end he tells of the band's gear being stolen on tour in America in 1995, the drive to San Francisco to replace it, and the single cassette they had with them for the drive, whose contents fed into how they approached OK Computer.
