This little piece has an interesting story.
Many years ago i played guitar for a brief period in a melodic rock group that tried to propose some original songs.
In this period i have written some original instrumental pieces but, after a live, a friend of mine says:
"Dude, one of the song is not an original, it remember me a song by Franco Mussida!"
And he was right! The melody of my 'original' song was identical to guitar intro of "In mezzo alla corrente", a beautiful song by Franco Mussida.
An unconscious plagiarism: probability I listened (and forgot) the song few years before.
Years later, i decided to reuse this simple melody for a simple guitar study (an homage to Mussida), named (obviously) "Into the flow".
