The Finnish guitarist Timo Korhonen has long championed contemporary music, and this Ondine disc from 2007 features his performances of solo guitar works by three composers. I'm not a fan of Henze and I came across this disc while exploring the music of Lindberg and Takemitsu, so I'll limit my review to the pieces by those two here.
Toru Takemitsu was probably the most important modernist composer of guitar music, and the instrument appears many times in his catalogue. "In the Woods" (1995) is one of the his last works, completed just four months before his untimely death. Cast in three movements, it is meant to be a musical representation of various places: "Wainscot Pond", "Rosedale" and "Muir Woods". Like all Takemitsu, it is slow and meditative, with only the briefest moments here and there of fast tempo. I personally find Takemitsu's guitar work pleasant but nothing to get excited about, as much as professional guitarists think it's the cat's meow.
Magnus Lindberg's "Mano a mano" (2004) offers a refreshing change of pace at first, as it is rather busy and more overtly virtuosic. However, it gets dull quickly. Lindberg's mature output is almost entirely for orchestra or for duos that he can treat like miniature orchestras. His idiom generally doesn't work on guitar. Towards the end there's a couple of minutes of decent music, but it's not worth waiting so long for. Not a major Lindberg piece at all.
