Jay-Z released his third album Vol. 2... Hard Knock Life on September 29, 1998. His first number one album, it spent five weeks at the top spot on the Billboard 200, more than any of his LPs since. Two decades later, the same magazine described the record as the moment "he transformed from respected New York MC to axis of American pop." For another installment of Silver Liner Notes, our 25th-anniversary series, we discuss the album's legacy with Andrea Duncan-Mao, All Of It's own senior producer and former MTV producer who covered Jay-Z's early career. And we take your calls.
