Born on October 30th 1930 Clifford Brown is often referenced as one of the most influential and talented jazz trumpeters of his generation. Despite dying at the young age of 25 he still managed to leave behind a sizable back catalogue spanning 4 years, which included a whole host of live performances and even a collaboration LP with the legendary Sarah Vaughn. This track entitled Yesterdays is taken from a 1955 record released on EmArcy, called ' Clifford Brown with Strings' and combines Brown's distinctive trumpet stylings with powerful string arrangements. Little was Mr Brown to know that 40 years later the introduction to this melancholic jazz number would be sampled and spliced by legendary hiphop producer and pioneering jazzy crate digger Dj Premier to form the main loop on KRS-Ones 1995 classic 'Mc's Act Like They Don't know'.
