Listening to music under a bridge

I saw the most amazing mini gig last night! The brass section of Tim Hill and Tongues of Fire -- two trumpets, two saxophones and a trombone -- played for about half an hour under the bridge by Kennet Mouth. I was informed that the acoustics under there were really good -- it sounded great to my untrained ear. It was also really atmospheric, under the bridge, with light bouncing off the water, geese and swans gliding by and people silhouetted against the sky. This was one of the best gigs I have ever been to!
