Have you noticed the blue tube hanging under the eaves of Brown and Brew? This "tuning tube" converts the soundscape at the intersection of Boston Ave and College Ave into a harmonic series in the key of E. The tuning tube was invented by Bruce Odland and Sam Auinger, of O+A. 
To help you keep in touch with the harmony and the beauty of the age of noise, we've set up a real-time web stream of sounds and video taken from this intersection. Click below to play the meditative drone of the Main Drag online.
The Main Drag can also be experienced in the physical world at the Sound Dial Gazebo. When the Sound Dial is in its resting state, it will play the Main Drag. Go check it out
