Oh, I know the music is a small part. I discovered the comic in the early 80s and have most of the volume one magazines (and the rest of volume one in various collections). Jaime's stories don't really kick off proper until after the Mechanix story, though a lot of the parts are there from the get go. The pro solar mechanic stuff etc is a great read though.
I'd love to have the first fifty set, but it's a bit expensive for me. I'll make do with the library trades.
That FCBD issue was something the seller threw in for free with my order. I'd never heard of it, but it was by JMS, so of course I had to give it a chance. Looks like an interesting comic, but I doubt I'll pick it up. I have too much to spend money on, at least right now.
