Other Interests

  • I am an enthusiastic guitarist and enjoy playing both electric guitar (jazz, fusion, rock) and acoustic guitar (classical, bossa nova, fingerstyle).
  • I also enjoy listening to music (see also my current musicshelf), reading (see also my current bookshelf), traveling, hiking, movies, games, attending concerts, and probably quite some more things.
