Jan. 1 Cowboy Mouth w/ Dash Rip Rock Waiting Room, 6212 Maple St. 9 p.m., $15, onepercentproductions.com When you were sitting there stoned, watching the movie Half Baked , a cover of Steppenwolf’s “The Pusher” played in the background at some point. The song was revamped by a little band called Cowboy Mouth, a New Orleans-based rock quartet with a reputation for putting on live shows equivalent to “religious experiences.“ Founding members Fred LeBlanc and John Thomas Griffith take their latest incarnation on tour to share an infectious blend of southern rock and punk influences. Formed in the early ’90s, Cowboy Mouth is notorious for playing more than 200 shows a year and displaying blatant admiration for its hometown. Basically, they bring Mardi Gras with them. Kicking off the 16th Annual Mardi Gras Tour, Cowboy Mouth gallops into Omaha for a night of welcome debauchery.
