I didn't mean to confuse you when I said the following: Berklee is w/in walking near you/Emerson not far/ Bu not far/ Harvard not far but depending on what type of walkers you are , other than Berklee you may need to T and would definitely for H, Somerville, etc.

"Berklee School of Music (or they may have something posted on their site or you could even call them ) and it is w/in walking distance for you:

Emerson College, Boston University, Harvard U

and also, music events in Cambridge/Harvard Square area -
Somerville - davis square/union square -
