Janne Schaffer is a guitarist from Sweden who according to the liner notes on the back of the album played guitar on every ABBA record. This is his first U.S. release from 1977. It’s a promo only album,I can’t remember where I bought it. It has two copies of a press release from the record company inside. The record and cover are in like new condition. It’s Jazz Fusion very similar to what Jeff Beck or Mahavishnu Orchestra was playing at that time. He is a greatguitarist ond the music on here is very good with bass ,drums,sax,and violin backing him up. No mention on the record who these musicians are.
