I understand starting from the beginning. But there are two reasons I don't want to do that.
1. After reading through the book, I am really interested in hearing the music that came out of Neal's head space at the end of his time with Spock's more than I am interested in the early stuff.
2. Often, when I discover a band after the fact, their earlier sound doesn't capture where my current tastes are, so the older stuff often sounds better when I can put it in context of their overall sound and evolution than if I heard the older stuff first. Take Nightwish as an example. I got into them during the Once era. I had heard a song or two of their older stuff, and it didn't click. But I got the two most recent albums at that time, and loved them both. Then after immersing myself in those, I was able to go back to the older stuff and appreciate it. I've gotten into a lot of older bands that way.
