My boyfriend is a musician and he's been really into jazz lately. His friend showed him this thing called "The Real Book", and my boyfriend has been obsessed since he saw it. I wanted to get it for his birthday but there's like six different versions on Amazon. Any recommendations on which version I should get? If it helps, he's a drummer. Thank you for any info in advance, I have no musical knowledge at all.
