No, they're not trying to tie Allston up in knots - that's just a side bonus. From a press release:
The Music Museum Of New England (MM/ONE) is launching the Boston Music Trail by unveiling the first of several markers honoring sites significant to the musical history of the city. The marker will be installed at 1325 Commonwealth Avenue in Brighton, where Aerosmith lived together and rehearsed in the basement when the band first moved to Boston in 1971 to begin its storied career. ...
The first phase of the Trail, involving six locations, is being funded by Music Drives Us, a foundation created by Ernie Boch Jr., of the renowned automotive family, to support music education, preservation and awareness throughout New England.
