There's no such thing as a bad Graham album from the 1960s. While Hat isn't necessarily the first one you should dig into, it offers the standard pleasures that you expect from his records: excellent, feverishly imaginative acoustic guitar playing; vibrant jazz-blues arrangements; and covers of blues numbers, Paul Simon, and Lennon-McCartney. He's just as capable of good-time blues ("I'm Ready") and a folk cover of "Getting Better" from Sgt. Pepper as dark, slightly dissonant instrumentals with a modal/Eastern flavor. As is the case with most of his '60s albums, it's very hard to find, especially in the U.S., where Graham did not have a record deal.
