Here are a number of links to a lecture course Gillian Rose did on Lukacs, Bloch and the Frankfurt School. Whilst the quality of the recordings are rather shoddy and Rose makes many of the same arguments in her books, people may still find them of interest.
Update — I didn’t record off the cassette myself so I assumed the lectures had the same titles as the files I converted and uploaded. After a little research,the Sussex library catalog names these lectures as the following:
Although the recording quality and lengths of the following are different, I think they are both copies of The Frankfurt School; Cassette 1, Marxist modernism
This means that the following lectures have not been included from the Frankfurt School Course:
‘Cassette 4, The battle over Walter Benjamin’.
Cassette 6, The search for style: Adorno, Kafka or Mann.’
The library also lists the following recordings from a different lecture series:
Sociological theory and methodology; Cassette 1, Introduction to critical theory
Sociological theory and methodology; Cassette 2, Does Marx have a method?
Sociological theory and methodology; Cassette 9, The unity of sociological thinking.
(cassettes 3-8 are not listed in the library catalog.)
