Frankie Dymon Jr. was a kind of 'project' led by Frank Dostal and Achim Reichel, previously members of The Rattles, one of the most well-known German beat groups, and Wonderland. Under the name Frankie Dymon Jr. they recorded one album in 1971, titled Let It Out, for which Reichel wrote most of the songs and produced the album (engineering was by Konrad Plank).
The album is a fantastic and rare German psych Kraut LP. Many of the tracks have very unusual arrangements. The psychedelic cover art is also notable. (progarchives)
