Diamond Records was a record label, based in New York City, which was founded in 1961 by former Roulette Records executive Joe Kolsky. Another Roulette exec, Kolsky's brother Phil Kahl, joined Kolsky in the venture the following year.Success for the label was slow but they got their first big hit in 1962 with "Loop De Loop" by Johnny Thunder. That record led to a distribution deal with EMI to distribute Diamond recordings on Stateside Records in the UK.
