The creation of the LP in 1948 allowed more or longer recordings per record, with approximately 22 minutes of music able to be played per side for a maximum of 44 minutes. Despite this, recordings of entire classical or operatic pieces often proved to be too large for one record, and thus album releases which consisted of two or more records were made to compensate. As such records were costly to make and sell, double albums and multi-record releases were largely limited to long-running works like classical music, and later, to live recordings and compilations. One of the first live double albums, as well as one of the earliest double albums featuring non-classical music, was "The Famous 1938 Carnegie Hall Jazz Concert" by Benny Goodman, a live recording of the titular concert at Carnegie Hall released in 1950 on Columbia Records. Studio recordings of operas have been released as double, triple, quadruple and quintuple albums since the 1950s.
