"A British pressing with a compilation of the best stuff really, I mean actually not only that but, these were all kind of semi hits for the people on it in America"

This quote by Eric Clapton is describing a British pressing of a collection album. He is suggesting that the album contains a few of the very best music from the artists included on it, and that the tunes were semi-hits in America. This suggests that the tunes were popular in the UK, but not also known in the US. Clapton is most likely praising the album for its quality and for presenting American audiences to some of the best music from the UK. He is also likely suggesting that the album is a great method to find brand-new music from the UK. Overall, Clapton is expressing his affection for the album and its ability to introduce American audiences to a few of the best music from the UK.
