Another solo piece, pi (1-2594), was performed in installments by the composer on 15 selected days in February 1999, in Evanston, Illinois, in Düsseldorf in 2000–2001 and at the Huddersfield Contemporary Music Festival in 2009 (with pianist Philip Thomas).
Pisaro has also devoted works to poets including among others, his harmony series, which functions as both a kind of poetic anthology and a collection of indeterminate scores, and July Mountain which is a translation of the poem of the same name by Wallace Stevens, into a score for field recordings and several layers of percussion.
It has been selected twice by the ISCM jury for performance at World Music Days festivals (Copenhagen,1996; Manchester, 1998) and has also been part of festivals in Hong Kong (ICMC, 1998), Vienna (Wien Modern,1997), Aspen (1991), Chicago (New Music Chicago, 1990, 1991), Glasgow (INSTAL, 2009), Berlin (MaerzMusik, 2010), Sonorités (Montpellier, 2011) and others.
He has held composer residencies in Germany (Künstlerhof Schreyahn), Switzerland (Forumclaque/Baden), Israel (Miskenot Sha'ananmim), Greece (EarTalk) and in the U.S. (Birch Creek Music Festival/Wisconsin).
Concert length portraits of his music have been given in Munich, Los Angeles, London, Tokyo, Mexico City, Seattle, Jerusalem, Madrid, Santiago, Vienna, New York, Brussels, Curitiba (Brazil), Berlin, Chicago, Düsseldorf, Zürich, Charleston, Toronto, Cologne, Aarau and elsewhere.
