I am an American and have lived in Vilnius for two years. I was a professional rock musician for 12 years and owned two night clubs in America. Your reporter who reported on Terminalas either has no experience in the night club business at all or was drinking a little too much of the local brew.
Terminalas has the worse music sound system of all the clubs in Vilnius for its size. But this seems to be a major problem when it is a Lithuanian-owned club. They seem to think this part of the club - sound system - is not very important. After being in the Terminalas club for 15 minutes one must run for the exits...not because of the volume as much as the bad [sound] quality.
The best music sound-system in Vilnius - and of all of Lithuania - is Gravity.
