Everyone on this board has a point in their life when they really started listening to music. It may have been triggered by a band, a song, a magazine, or a friend. It may have clicked in an instant or intangibly grown over a period of years. Personally, it's hard for me to pinpoint a time because I've been surrounded by music my whole life. My parents met at music school. My sisters and I began learning our first instruments at the ages of two, three, and five. My whole family became somewhat famous in my home town for playing music at weddings, churches, holiday and business parties, etc. At some point we've all made money, if not a living, by playing and/or teaching music.
I've always struggled to reconcile myself as a music listener with myself as a classically trained musician. Ever since I started listening to the Flaming Lips and Radiohead when I was twelve--long after I was able to understand basic music theory, not to mention read music and play multiple instruments--there have been two battling angels on my shoulders: artist versus artisan, creativity versus skill, vocation versus occupation. I went through a phase when I didn't know there was more to music than practicing a lot. I also went through another phase when I thought any type of musical training impeded all creative growth. Now I understand that it isn't as black and white as any of that. This list is an expression of me coming full-circle, a snapshot of the period of my life where I maybe started to understand how the one informed the other. It may or may not be what you or even I expect.
What you won't find on this list: technical mastery for its own sake and gratuitously complex time signatures. I'll watch professional sports if I feel like ogling at an amazing feat of human skill. Technical mastery in music has been boring to me since middle school, and your song in 13/8 is probably a gimmick.
What you will find on this list: detailed arrangements, clever compositions, and tight musical interplay serving an artistic vision shared by people who listen and react well to each other while performing.
Summer is a very busy work time for me, so I'll be updating whenever I get the chance. There is no set number or order of entries. Feel free to mention your own favorite musician-y albums.
