"Piano" is an instrumental piano album by legendary Swedish composer and ABBA founder Benny Andersson. The album contains 21 tracks: new interpretations of ABBA classics, musical pieces, and previous solo work. While recording this instrumental album, Andersson realized how integral these songs are to him. "It feels a bit like I'm performing my memoirs... Stripped of all the bells and whistles, drums, guitars, and vocals, I gradually got to the core of these pieces."
