The binge and purge method of partying and spiritual redemption was a favorite method of maintaining a healthy chi in my more elastic 20s. Blame it on living in New Orleans but I actually think indulgence followed by abstention can benefit the body electric. Phatsy Kline's Parlor Lounge has its own (albeit weekly and decidedly more low-key) version of Mardi Gras, too, starting at 6 p.m. with its Phat Tuesdays series of free shows during happy hour. This week's act is That Buckin' String Band, a quartet of pickers and singers who play a mix of originals and covers on the uke, the mandolin, the upright bass and all things in between.
