As I understand it, there are two theories about Alice Coltrane...

a) she channeled the spirit of dead husband and jazz genius John from beyond the grave, allowing him to create masterpieces posthumously, and

b) she was driven insane by the loss and the music helped the denial, a jazz-balm for her existential pain (ie she was mad as fuck)

I know where my money is. This track is some sort of reworking of John's signature tune and starts off sensibly enough (well, for a jazz track) - and then the billowing clouds of string descend, some kind of crazy mixed up meettyfoour...I don't think it's the maddest of her tunes, it's quite accessible in fact, but it does seem to illustrate well the idea that all was not well...
