Skipping or not, a 10″ Latin jazz EP by Perez Prado and His Orchestra is always worthy of your $1. Titled Mambo By the King, this 1953 release featured a sister, pressed as a 12″ (which also contains four additional tracks). This, slightly shorter version still manages to contain some of Prado’s well-known, and unforgettable classics (Perdido, Cuban Mambo, and Mambo Jambo come to mind). Released the same year as his famed Havana, 3 A.M., By the King was one of the many (extremely cheap, yet skippable) gems I recently found in the bargain bin at my local hut. Let the fun begin.
The Prudent Groove 
This is from 1953, not 1956. The 1956 date refers to the 12″ version, which was released to keep this record available after the industry-wide decision to kill off the entire 10″ format during 1955.
Thanks for the informative tip!
