Strauss and Haydn are served alongside the theatre's own piece - a collage of work from 11 composers delivered by the orchestra as well as from instruments made from scrap material. Fri (Sha Tin Town Hall auditorium) and Sat (Tsuen Wan Town Hall auditorium), 8pm. $80-$180. Apr 6 (Cultural Centre Concert Hall), 3pm. $100-$200. All Urbtix. Inquiries: 2721 2030
