Super K Production

Super K Productions was a 1960s American recording production company under Buddah Records, headed by producers Jerry Kasenetz and Jeffrey Katz, whose groups specialized in bubblegum pop. Their biggest successes were The Ohio Express, The 1910 Fruitgum Company, Crazy Elephant and The Music Explosion. Super K also had their own label of the same name in 1969 operated under Buddah Records, but it did not last as the bubblegum genre had already started to decline in popularity.

Not a company to depend on double-sided hits, many (but not all) Super K-produced singles were pressed with B-sides of either tracks recorded backwards or studio group instrumentals. This method was also employed earlier by producers Phil Spector and Joe Meek as a way of pointing a radio DJ to the "right" side of the singles.
