Infinity Hall is a stunning concert hall up in the tiny northwestern Connecticut town of Norfolk. The story of how the owners renovated an old building and turned it into a hall with incredible acoustics, a hip cafe, and a destination for music lovers is itself a great story. Now the owners are looking at opening another music hall on Front Street in Hartford. This is exciting news if it actually happens. Because the Front Street project, part of a massive attempt to pump new life into downtown Hartford, has sat vacant since it was completed two years ago just as the economy was tanking. Infinity Hall is teaching us all a priceless lesson. It takes more than buildings to re-make a city. It takes creativity, both ideas and energy. Let’s hope this idea works. It’s exactly the kind of idea that revitalized parts of Portland, Or., when indi bookstore Powells took over a warehouse. Next thing you knew there were brew pubs and restaurants and condos all over.
