Let's listen to a beautiful song from one of the earliest 45rpm records ever made. RCA Victor introduced this format in 1949 and they were all coloured vinyl by then. There is a color to differenciate each musical style and song language. The recording techniques feel much like 78s, because this recording was made prior to the RIAA specifications introduced in 1953 to regulate all recordings.
78 rpm : RCA VICTOR - 25-1158-A
45 rpm : RCA VICTOR - 51-0070-A
I have several colors. My favorite is pink! No wait, turquoise! I can't pick!
