I have not experienced much live concerts but those I have were nearly all great:
1. PINK FLOYD 1994 Prague, we had been waiting for hours in the rain before the beginning but it was worth waiting. Very complex and perfect.
2. PETER HAMMILL twice in Prague, once with the group (1994), once alone (1992). Fantastic. On the other hand, once in Vienna (2002) it was horrible, a small hall full of smoking intellectuals that I nearly could not hear anything..
3. PETER GABRIEL in Bratislava (199?). Excellent show.
4. FISH in Ostrava (1994). I do not know who was sweating more, he or the audience. Absolute 100%.
5. COLLOSEUM in Bratislava (1996). It was great to see the drummer JH. One of the best ever.
6. JOE ZAWINUL, LARRY CORYEL and many others in Bratislava Jazz Days Festivals.
7. Don Giovani, opera of WAM
...Chuch Berry r'n'r show, I do not remember when it was...
