Alex you presented this album, and I bought it; this album projects the mood and feel of these places (63rd and Cottage Grove, 45th and Calumet, La Salle street) when I was a teenager exploring them.
This is the power of music; John Wright projected these streets in his music so well, that you could re-experience strolling down them once again; they were among the the hippest streets in Chicago, but now, they only exist in the memories of people who lived there at that time, and enjoyed life as it was lived on those streets.

The comments below this concur with my thoughts about this album, and that part of Chicago at that time.
