Helmut Lachenmann is best known for the musique concrète instrumentale of his middle years, but the three works on Got Lost come from before and after that phase. The early Streichtrio of 1965 stands next to two large pieces from the turn of the century, the piano work Serynade and the song Got Lost for high soprano and piano. The programme covers more than four decades of his work.

Lachenmann was born in 1935. The soprano is Yuko Kakuta, who was the soloist in a staged production of Got Lost and took it to the Theater Bern, the Salzburg Biennale and the Frankfurt Opera, among other places. The pianist is Yukiko Sugawara, a founding member in 1994 of the saxophone, piano and percussion group Trio Accanto. The string trio is played by trio recherche, formed within the Freiburg ensemble recherche, which has existed since 1985. The recording is a production of Südwestrundfunk.

Got Lost (2007/08), at 27 minutes, sets three texts: four lines by Friedrich Nietzsche, the poem All Love Letters Are Ridiculous by Fernando Pessoa, and a short note in English lamenting a lost laundry basket, which gave the work its name. Lachenmann described them as three only seemingly unrelated texts, stripped of their lofty, poetic or mundane diction. All are given to the same sound source, a soprano voice singing "any old way", and sent into a constantly changing field of interval, resonance and movement. Serynade (1997/98), about half an hour long, is the most extended piano work here, and the Streichtrio lasts under twelve minutes.

The thinking behind all three goes back to a principle Lachenmann formulated in 1970: sound taken as "the characteristic result and signal of its mechanical origin" and of the energy needed to produce it. Noise-like instrumental sounds are compared for likeness and contrast, then catalogued into categories and families. These become the basis of a kind of motivic development made of noises and sounds.
