Lost Highway, London

Olga Neuwirth has emerged over the last decade as one of the leading members of an outstanding generation of Austrian composers who are now in their late 30s and 40s. They are all very different musical personalities, and Neuwirth is perhaps the most singular of the lot. Little of her large-scale music has been heard in Britain, but English National Opera is inaugurating its short season at the Young Vic with the UK premiere of Lost Highway, Neuwirth's 2003 music-theatre piece, based upon David Lynch's psychological thriller of the same name. Neuwirth takes Lynch's screenplay virtually intact and, using multiple video projections as well as real-time digital transformations and projections of the voices and instruments, creates a world that has the same dislocating ambiguities as Lynch's original film. Staged for ENO by Diane Paulus, it won't be opera as we know it, but something strange and unique.

Brazil Plus, London

The ensemble Lontano and its founder conductor Odaline de la Martinez have made a speciality of seeking out composers who have slipped through the nets cast by other performing groups. The focus of their latest concerts is the 20th-century music of Brazil, particularly that of Heitor Villa-Lobos and his lesser known contemporary Francisco Mignone. They're joined by the Brazilian pianist Clelia Iruzun performing works including Villa-Lobos's Choros No 7, one of his finest works, as well as the ninth of the Bachianas Brasileiras series, Mignone's set of Six Preludes for piano and the UK premiere of his Third Fantasia for piano and strings. There's new British music to be heard too - premieres from Silvina Milstein and Jeroen Speak.
