Brought to you by Blackfire Research….On this day in 1963, the classic pop single written and produced by infamous record producer, Phil Spector, “Da Doo Ron Ron,” peaked at number 3 on the US singles chart. The song, released in March, was performed by The Crystals, a prominent act in the “Girl Group Era” of the early 1960’s. The Crystals were well known before the single, but “Da Doo Ron Ron,” as well as “Then He Kissed Me,” also written and produced by Spector and released in July of that same year, made the group a household name. For the composition of “Da Doo Ron Ron,” Spector used his signature production technique. By using a multi-track recording system, Spector was able to build the song in layers, ultimately achieving a result he called a “Wall of Sound.” This “Wall of Sound,” created by a large ensemble of musicians, resulted in fuller, more dense harmonies, and therefore, ensured more engaging music for AM radio play and jukeboxes.
