One song that everybody needs to hear this week is “The Mighty Flood” by the Batture Boys also known as longtime collaborators Tommy Malone and Ray Ganucheau, now officially working as a duo. The first track from their forthcoming album, released this week as a free download.

Written by Malone, the Katrina-themed song is a gritty blues shuffle that calls up some bad memories (“Called up the office and talked to their answering machine/ They said please hold, and all that I’m holding is my dreams”) before celebrating the city’s resilience (“I know that blood is thicker than water”).

Malone and Ganucheu played everything on the track save the drums, which are by Jimmy Paxson. Producing sessions is Jim Scott, who’s won multiple Grammys for his engineering work with Santana, the Red Hot Chili Peppers and the Dixie Chicks, and is lately producing Wilco. The Batture Boys should have an album and some live dates before the year is out; meanwhile Ganucheau is preparing to rejoin the Continental Drifters at Tipitina’s on September 12.
