The OPERA GUIDE is intended to stay accessible without charges and to remain ad-free. In order to maintain this policy, it depends, however, on donations. Your voluntary contribution (as little as 6 US$ or more) will help this non-profit project to carry on.
In return for your donation you will get temporary access to Audio-files, Video-Clips, historical recordings (MP3) , sheet music and to selected Media-echoes from the "Highlights" section.
The duration depends on the amount of your support.
(6 US$ = 1 month / 12 US$ = 3 months / 18 US$ = 9 months / 24 US$ = 12 months)
With an annual returning donation of 18 US$ you will be given permanent access.
