Mr. Lindberg’s music is oustanding in its incorporation of a wide variety of twentieth century techniques—serialism, electronics, pastiche, spectralism, neoclassicism—within a coherent oeuvre. Among Mr. Lindberg’s breakthrough works is Action—Situation—Signification (1982), which drew upon musique concrète. Kraft, written in 1985, a concerto for the Toimii ensemble with orchestra, and Ur (1986) further explore the synthesis of electronic sound and instrumental conventions. In the nineties, Mr. Lindberg has gradually moved from electronic sound to a reinterpretation of conventional harmony and form. In 1994, a major orchestral work, Aura—in memorium Witold Lutoslawski, was premiered in Tokyo to much acclaim. Notable recent works include the Piano Concerto (1994); Engine (1997), written for the London Sinfonietta; and Related Rocks (1997), an IRCAM commission.
