The violin concertos by Bartók and Ligeti are two of the greatest of the 20th century, and in this two-disc set they frame another Hungarian concerto, Peter Eötvös's Seven, which he composed in 2006 in memory of the seven astronauts who died in the 2003 space shuttle disaster. The work is dominated by the number seven, and the series of accompanied violin cadenzas that forms its first part is dedicated individually to the astronauts, though the elegiac purpose of it all only becomes really clear towards the end of the second part when the violin settles into a drawn-out lament. Patricia Kopatchinskaja is clearly an immensely able violinist, and she projects the Eötvös with wonderful confidence, but her rather brittle style is better suited to the sparkling polyrhythms of Ligeti's work than to Bartók's brand of neoclassicism, which sometimes seems to get short measure expressively, especially in the central set of variations.
