You are probably familiar with Echo Bridge and the surrounding Hemlock Gorge as a great scenic landmark and walking area, but it is also associated with music. Recently it was the scene for a short music clip that exploits, via saxophone, it echoing effect. You can view the video HERE.
Also, "Echo Bridge" gave its name to a bluegrass band that played around the area (greater Boston) for about a dozen years. The band is now defunct, but it issued a CD that is now on YouTube. You can find it by Googling "Echo Bridge Bluegrass" or by going directly to this video page.

(Full disclosure: Mark was a member of the band, singing, playing mandolin, and writing several of the songs.)
