Melvin McClelland^[4] (June 1, 1945^[2]-July 26, 2010^[3]) was a rhythm and blues singer known for his 1973 song "Reward/Synthetic Substitution",^[5] the B-side of which was heavily sampled^[3] in at least 94 hip hop songs such as "Real Niggaz Don't Die" and "Alwayz into Somethin'" by N.W.A, "O.G. Original Gangster" by Ice-T, "O.P.P." by Naughty by Nature and more recently "My Life" by 50 Cent, Eminem and Adam Levine.^[6]

Born in 1945^[2] in Chicago^[1] as Melvin McClelland,^[4] his career didn't begin with music; rather, in the Armed Forces.^[7] After spending a few years singing in Naval bands, he departed the Navy in the mid-1950s. From there, he went from stage to stage until the early 1970s, when in an attempt to boost his career prospects he visited a Queensbridge concert hall intending to use it for self-promotion.^[7] Whilst awaiting a meeting with the hall's owner, he encountered the mother of Herb Rooney and it emerged that he wanted a singer to record one of his compositions.^[7] After an informal discussion with Rooney himself, Bliss hit the studio to record it;^[7] the result was Reward. That song's B-side, "Synthetic Substitution", became one of the most sampled songs of all time.^[8] Bliss' label, Sunburst Records, was a sister company of Opal Productions, and in 1974 it went bankrupt, taking Sunburst Records with it;^[7] in doing so rendering Bliss a one-hit wonder.

In 2011, a documentary about him, Synthetic Substitution: The Life Story of Melvin Bliss, was released by Peripheral Enterprises. It was produced by Earl Holder.^[1]

On July 17, 2010, it was announced by Melvin Bliss, Jr. that Bliss had suffered a heart attack and had been rushed to NewYork–Presbyterian Hospital.^[9] Just over a week later, on July 26, 2010, it was announced that Bliss had died.^[3]
