Quick Summary

Asylum Records label.

The LP, or long-playing record, is a microgroove phonograph record designed to play at 33\u2153 revolutions per minute. Introduced by Columbia Records in 1948, the LP revolutionized music recording and consumption. These vinyl discs could hold approximately 25 minutes of music per side, a significant improvement over the older 78-rpm shellac discs, which only lasted about 4.5 minutes per side. This extended playing time allowed for longer musical works, such as symphonies, to be played continuously on a single side, enhancing the listening experience. The LP format, along with magnetic recording and later stereo advancements, paved the way for the high-fidelity sound systems that became popular in the mid-20th century.1234
