The movements in such works are often linked by improvisatory solo interludes, as in the Second String Quartet of 1966 . Although Láng also worked briefly with electronic music as early as 1974 ("Surface Metamorphoses"), he turned seriously to this medium beginning only in the late 1990s, for example "Esteledés" (Nightfall, 1997), which uses live electronics to manipulate sounds of a trumpet and Korean bell . More recent works with electronics are the "Capriccio metronomico" for tape (2001), and the Third Chamber Cantata, "No Man Is an Island", to words of John Donne (2001), for soprano, five instruments, and tape .
