Since the ‘90s, DJ Shadow has been known for his scratching, sampling and crowd-inciting beats. The musician and producer’s 1996 debut album, “Endtroducing.....” is considered one of the best albums of all time. Now, nearly 30 years later, he’s releasing a new album, called “Action Adventure.” DJ Shadow talks to Tom about what it felt like to put out “Endtroducing.....,” how his views on sampling have changed over the years, and what’s required to make compelling instrumental music.
