Record Plant [SEP] Introduction
During the 1980s, they sold the New York and Sausalito studios; the former closed in 1987, the latter in 2008. The Los Angeles studio, which remains in operation, was purchased in December 2016 by songwriter/producer Philip Lawrence. The Record Plant in New York was the first studio to give recording artists a comfortable, casual environment rather than the clinical setting that was normal practice through the 1960s. Kellgren and Stone brought this same vision to their Los Angeles and Sausalito properties, adding a Jacuzzi and billiard table. Stone later said of Kellgren, "He single-handedly was responsible for changing studios from what they were—fluorescent lights, white walls and hardwood floors—to the living rooms that they are today." The Los Angeles location has since added VIP lounges.
