Hello, There is a wonderful piano piece by Rihm that I performed a couple
of times in Toronto entitled Landler (1979).  It is, as the title suggests,
a slow dance in 3/4, and it is dedicated to his more senior composer Wilhem
Killmayer.  Coincidentally the piece resembles Killmayer's style a lot in
my opinion.  It is an extremely beautiful, sentimental and honest piece (I
realise these are completely subjective terms), but it is not quite as
innovative or 'avant-garde' as his other pieces for piano that I have seen,
or at least the ways in which it is innovative are not as obvious.  I have
also heard a string quartet and a piece for violin and orchestra by Rihm,
both of which did a lot for me.

Regards,
John
