Melvin, and the Philadelphia label as a whole, are now recognised as having shaped the sound of disco music in the mid 1970's. Tracks such as "The love I lost", "Where are all my friends", "Bad luck" (baaaddd bassline) and the original of "Don't leave me this way" (also recorded by Thelma Houston were a defining style for the group.
Failing Philadelphia label by the very end of the 1970's, and contractual difficulties, caused Melvin and group to move to the ABC label, and later Source (a sub-label of MCA). From this period, listen for disco classics "Baby you got my nose open" and "Tonight's the night" (which features the vocals of Sharon Paige).
