“Allston Pudding” covers the local music scene, focusing on discovering and promoting the local bands that don’t get a mainstream mention, never mind a real club to perform in. This review liked the crowd, the high basement ceilings of the literally underground Thieve’s Grotto, and all the bands. The ‘Foxes as Pets’ members are all of 16 and 17 years old, and must have borrowed mom’s car to make the drive all the way from Scituate. Thieve’s Grotto takes place in a seriously undisclosed location, somewhere in Allston.
