Splendid Zine sez'
"At the intersection of Mass. Ave and Brookline Street, the sign demarcating Mark Sandman Square stands as a landmark for those seeking rock music in its purest form, as its namesake once passionately delivered."

So I just noticed this sign today, while I was walking across Cambridge (on my way to work).
For those of you who don't know - Mark Sandman was leader singer of Morphine, who passed away in 1999 and I knew that there's a square dedicated to him either in Cambridge or Boston, but I had no idea that it was right next to my place of work.
