Other than from friends, I find out about more good music from the playlists of baristas than probably any other source. It's how I found Sufjan Stevens, The Kings of Convenience, Dzihan and Kamien, Neutral Milk Hotel, and a bunch more things I can't remember right now. After breakfast on the mornings that I get up with the wee child, I take him and the dog on a walk to any one of the roughly 47 coffeeshops within a ten-block radius of my house; on Friday morning that Talking Heads song that goes "Hi! Hi-Hi-Hi-Hi-Hi! Hi-hi!" was playing when I walked into Tougo (which is by far the best of the 47 coffeshops I can walk to). Right after it was this instrumental song I had never heard before, it had sort of a 60's-70's jazz-rock vibe; the lead guitar was really present in the mix, but at the same time had a whole bunch of reverb on it, with the rest of the band unusually quiet. The guitarist was playing this really simple, really catchy melody which tied up at the end of each phrase in a way that I can't describe other than to say it was incredibly satisfying to listen to.
My college math professor Shahriar Shahriari once remarked as an aside during class, "there is a lot of math in the world. People don't realize how much math there is." He meant that most people's awareness of math essentially encompasses arithmetic, algebra, plane geometry, trigonometry, and calculus, which is the rough equivalent of someone's awareness of literature being comprised entirely of Greek tragedy, some medieval Islamic texts, and 17th century British novels that some people argue were actually written by Russians. Similarly, it frequently boggles my mind how much good music there is that I'm totally unaware of. It makes me both happy, for all the good music there is, and sad, because how on earth could one listen to it all, or ever compete for attention with all the rest of it?
