Quite a wonderful recent addition to my collection, this. The story of Rodriguez is quite amazing and I strongly recommend doing a little bit of research via your search engine of choice.
I Wonder taken from the 1970 album Cold Fact is a ragged, soulful, folky rotation ’round a cavalcade of choruses. The playing is a little raw and ropey, but that certainly adds to its charm. And along with Rodriguez’s soulful vocal, it deserves to be buried treasure no more.
