A quick description from http://www.tba21.org/program/current :

“T-B A21 presents its most ambitious public project to date in Vienna. A platform for contemporary music and composition, The Morning Line by Matthew Ritchie with ArandaLasch and Arup AGU is a public art structure – 8 meter high and 20 meter long, built of 20 tons of coated aluminum.
27 sound artists have contributed compositions, specially conceived for the pavilion’s architecture, which filled the sonic landscape of Schwarzenbergplatz during the pavilion’s first 6 months’ residency. Over the coming winter months, The Morning Line will be shown without its sound component, getting ready for a new season of compositions in Spring 2012.”
