In which format, introduced in 1948, was the album Showcase released in?
LP record The LP (from "long playing" or "long play") is an analog sound storage medium, a vinyl record format characterized by a speed of 33 ⁄ rpm, a 12 or 10 inch (30 or 25 cm) diameter, and use of the "microgroove" groove specification. Introduced by Columbia in 1948, it was soon adopted as a new standard by the entire record industry. Apart from a few relatively minor refinements and the important later addition of stereophonic sound, it has remained the standard format for vinyl albums.
Ballads (John Coltrane album) Ballads is a jazz album by John Coltrane. It was recorded in December 1961 and 1962, and released on the Impulse! label in 1963 as A-32 (mono) and later AS-32 (stereo). Critic Gene Lees stated that the quartet had never played the tunes before. "They arrived with music-store sheet music of the songs" and just before the recordings, they "would discuss each tune, write out copies of the changes they'd use, semi-rehearse for a half hour and then do it". Each piece was recorded in one take, except for "All or Nothing at All". In 2008, the album was a recipient of the Grammy Hall of Fame award.
