Wall of Sound is a new and used CD and record store located on E Pine st one block east of RT 5. This store specializes in experimental, electronic, and world music. Very interesting selection of music can be found here and you can listen to everything before you buy it. There is a small collection of used records also.
What makes this store interesting is that it seems to share the space with Comfounded Books which sells graphic novels. Very fun store to peruse through. Check out the experimental music selection.
