What about 'All That May Do My Rhyme?'
I loved this movie, but I do have one complaint: it leaves viewers with the impression that Roky didn't record any music at all for decades. The film completely skips All That May Do My Rhyme, released in 1995 and considered by many to be his best album. The film should have at least referenced the recording and release of this album. How did they get him into the studio? Was it recorded during a rare lucid period? What are the thoughts of the musicians who played with him at the time? We'll never know, or at least not from watching this movie.
