Multiple groove phonograph record (1898 – )

A multiple groove record has two or more parallel sets of grooves on one or both sides, allowing extra or hidden tracks to be added. On a disc that has multiple grooves, which track the listener hears depends on where the stylus is placed.

The first commercial record to use such a technique was a very early Berliner record released in the UK in 1898, ‘Puzzell [sic] Plate’ with two piano solos. Other early releases included ‘fortune telling’ records with different scenarios.

Later examples include the Monty Python album ‘Matching Tie and Handkerchief, issued in 1973. On early pressings, both sides were labled as ‘Side 2’, but one side had a pair of grooves.

The 12-inch single version of ‘Pop Muzik’ by M in 1979 was credited on it’s cover as the ‘first double-groove single’ as Side A and B were on one side.

Multiple groove 12-inch LPs and 12-inch singles continue to be occasionally released.
