Here you got that wonderful song from Sam Raimi’s Evil Dead II (1987), performed by Pablo Thonon and originally composed by Joseph LoDuca. This video was recorded live at Rockaway Studios (Spain) on July 12, 2016. The real name is “Dancing Game”, commonly (but mistakenly!) called “Ash’s Dream”, the reason being that this piece is the second one within a suite from the same composer (“Ash’s Dream/Dancing Game/Dance of the Dead”). There is even a piano sheet on the internet where the title also says “Ash’s Dream”. You can get the sheet HERE.
