The Bee Gees

By the picture on this L/P cover I would imagine that this must be an early set of recordings On The "BG's"....Sooooooo off to "Google"

 Horizontal is the fourth studio album by the Bee Gees, and their second album to receive an international release. The LP was released in early 1968, and included the international hit singles "Massachusetts" and "World". 

 The influences displayed on the album range from The Beatles to baroque pop.

Definitely a different Bee Gee's Sound !!!
