A few years ago I had a ticket to see Alice Coltrane at the Barbican, but sadly she died just a couple of weeks before she was due to play. So I have to congratulate the Barbican for not giving up on her music, by bringing over the Ashram Community Singers from the LA-based community which Alice founded in the 1980's, to perform her music which was released this year by Luaka Bop as
World Spirituality Classics 1: The Ecstatic Music of Alice Coltrane. And very good it is too.
However, I'm not sure this 'gig' is for me, as there are certain stipulations the audience are required to abide by, including not drinking alcohol before or during the event, and having to leave your shoes at the door. This event also encourages the audience to 'join in, chant and sing along' - although it's not mandatory - and there will be complimentary vegetarian food provided after the show (though they don't say if you'll be allowed to eat it after you've put your shoes back on or not).
Anyway, if you exist on a higher spiritual plane than I do and you fancy going, you can get tix here (nb. it's not actually at the Barbican but up the road at LSO St Luke’s)
