This event takes place overnight.  Audiences are free to come and go as they wish.One of the ideas central to Cage’s philosophy was asking us to consider the way we listen to and perceive music. Monumental in its duration, this performance of Cage’s Organ2 / ASLSP challenges the traditional parameters of a concert and asks us to choose our own path to engage with the music.

Presented by organist Parker Kitterman and others throughout the evening and into the early morning hours on Nov. 4, Organ2 / ASLSP will be performed on the powerful Curtis Organ housed in Philadelphia’s historic Christ Church.

Cage’s work is the subject of one of the longest-lasting musical performances yet undertaken: The current performance of this piece began in 2001 at St. Burchardi church in Halberstadt, Germany, and is scheduled to have a duration of 639 years.  The title stands for “As SLow(ly) and Soft(ly) as Possible” and also refers to “Soft morning city. Lsp!” (from James Joyce’s ‘Finnegans Wake’).
