React is the third collaboration between American ambient pioneer Robert Rich and DiN label founder Ian Boddy. However, unlike their previous two studio outings on the DiN label, Outpost (2001) and Lithosphere (2005), this is a record of their first ever live performance at the Star's End Radio Show 30th Anniversary Celebration Concert in Philadelphia in June 2007. The music ebbs and flows from abstract soundscapes through gentle reveries to up tempo sections that combine thunderous analogue bass and glitchy percussion overlain with a mesmerizing mix of keyboards, flutes and gliss guitar. A truly unique concert performance by two of the most accomplished musicians in modern ambient electronica.
