You can read and enjoy Adorno in bits without swallowing a whole overarching theoretical foundation. As he also often wrote that way.

Minimia Moralia for example is a collection of more personal and essay form writings.

Also I absolutely love Negative Dialectics as a piece of theoretical writing but I am not convinced it fits into the standard "Frankfurt school" label. It's more about epistemology than it is about culture.

(He was, however, more than a bit of a snob. I wouldn't take his musings on culture at face value unless you truly believe -- like he did -- that jazz and other popular music is just intrinsically and objectively worse than Bach forever and always absolute truth. Ahem.)
