a bit obsessive

When I was in my late teens I heard some keyboard sonatas be Padre Antonio Soler (above), performed on the radio by Virginia Black. I found them both startling and beautiful and sought out the scores of the ones I had heard. Having those few wasn't enough though. I needed to have them all, and managed to source the spanish publisher's retailer in London. I bought the full set. Each volume was more expensive than I could really afford, but I bought them nevertheless. I became obsessed with the composer. I taught myself Spanish. I bought a facsimile his treatise on harmony. That cost me nearly fifty quid, which was well beyond my means.The eighteenth-century Spanish is so strange that to me it is almost unintelligable, and I've still not been able to read the book. At Uni I put my obsession to good use; I wrote two research papers which comprised a study of his keyboard works. I immersed myself in the history and culture of Soler's world and compared these with other European cultures of the time. I set Soler's sonatas in the context of the wider genre, and looked at their origins. For me it was all-engrossing and fascinating.
Genealogy became another of my obsessions. My family was such a picture of fucked-up-ness that it's difficult to describe. We didn't seem to have any relations. I wanted to know why. Initially I would trawl the archives every other Saturday or so. I became obsessed to the point that I went every evening after work, and every Saturday, for about eighteen months. Imaginary images of the family fossils would preoccupy my mind, and these would be flying round in my brain together with all the other thoughts that have always inhabited it. Now I know everything I want to about my antecedents, and will probably never look again.
Earlier this week I discovered youtube. Eureka. I found all sorts of things I used to have recordings of, and other things that I'd intended to listen to. So no, not content with half a dozen pieces, I have accumulated a listening list of over four hundred pieces in the few days that I've been looking. I expect the list will more than double over the weekend.
This sort of behaviour is apparently typical of aspergers. I expect it's the product of an active mind.
