House Of Blues Boston information, This Summer, the face of Lansdowne street is going to change. Axis, Avalon, Embassy, and Modern will be closing down to combine into a single new facility. The new House of Blues Boston will be a roomy 2500 seat upscale music venue. This venue (and the 3 restaurants which will be a part of the facility) will change not only the face of pre- and post- Sox dining; but also allow national acts to perform at sizable, comfortable, and intimate venue.
