Adelphi Records

The label name was crafted by Rosenthal to suggest a combination of the Greek oracle, nearby Adelphi, Maryland, as well as a tip of the hat to a John Fahey song, "The Downfall of the Adelphi Rolling Grist Mill". Extensive field recordings were begun in 1964 and expanded to include film documentation beginning in early/mid 1969, including sessions in Chicago, St. Louis, Memphis and the Mississippi Delta. In the 1970s, the label began issuing folk, jazz and blues-rock albums. The latter were significantly important to the development of that genre. In the mid-1970s, two of Adelphi's biggest selling artists were the Nighthawks and the Rosslyn Mountain Boys. Towards the end of the 1970s the label's sales and growth had significantly expanded. This was particularly marked in the early 1980s, when Adelphi established its wholly owned subsidiary label, Sunsplash Records, predominantly to issue Jamaican reggae performances from the 1982 Reggae Sunsplash Festival. Musician signings continued into the 1990s and, after a short hiatus, resumed in the 2000s with studio sessions in New Orleans by Ken Swartz & The Palace of Sin, and in Silver Spring, Maryland sessions with the Rose Sheehan Group including vocals by Lisa Null.
