On this the fourth anniversary of Katrina, live music seems to be hard to find, at least during the day.  All week, I have heard about a “Festival” in Congo Square, but it wasn’t until this morning that I found out- there will be bands from 1-4 PM.  And good ones at that- expect to hear Luther Gray and Bamboula, the Rebirth Brass Band, Tyrone Foster Choir and the Free Agents Brass Band.
