Talking of the Troupe book (‘Miles and Me’, not the autobio) at the time it came out I remember attending a book launch/concert at a very nice auditorium in the LA area with Mr Troupe doing the intros with a stellar Miles tribute band including Bennie Maupin, Adam Holzman and Patrice Rushen. They played some of the Bitches Brew era stuff and it was great to hear Maupin in that context.
The Paul Tingen book is an excellent read ! Particularly good for the period up to ‘Agharta’. For the later period, I like George Cole’s ‘The Last Miles’.
