I've just finished the Miles Davis autobiography, pretty much presents itself as a character study of one 20th century music's most influential figures, and really digs in and talks about what the jazz scene was really like in the 1940s-50s.
Getting through Homage to Catalonia, enjoying the historical/political context of it, Orwell had that perfect mix of concise yet perfectly descriptive writing, especially when he was on the ground living through what he wrote (before 'Homage...' I had finished 'Down and Out..", and thoroughly enjoyed it).
I would love to pick up 'Infinite Jest' again, it has grabbed me with the small amount I have got through. Wallace wrote with such heart, and a kind of hopeless/paranoid humour.
I need the short-snappy books of late, too attention-deprived to battle it at the moment.
