Grenager works both as composer and musician. She has been working professionally since 1995 with commissions from a.o. Cikada, Ensemble Ernst, Trondheim Symphony Orchestra, Bodø Sinfonietta, Nordic Music Days, Fylkingen and Affinis ensemble. She has had portrait concerts at the festivals Ultima, Borealis and Ilios and her works has been performed at festivals and concerts all over Europe. She finds it important that the musicians own voices and choices are reflected in the performances of her works but simultaneously that the core of the work is clearly defined from her hand. This has resulted in a great variety of notational techniques and richness in detail in the different scores. Grenager«s work as performing improvisational musician has also influenced her compositions. She tours extensively all over the world with the improvisation bandsSPUNK, Lemur and with Sofia Jernberg. She has also cooperated closely with dancers, visual artists and actors.
Grenager participates on some 20 recordings as composer, musician and producer a.o. "Affinis-suite" (+3db), "Slåtter, slag og slark" (Euridice) og "Systema naturae" (Øra), and with SPUNK (Rune Grammofon), Lemur (+3db) og Jernberg/Grenager (olofbright).
