The Zoo Bar isn't throwing a big outdoor party this year — but it is celebrating its 32nd anniversary with a week of indoor shows that starts with a last-minute addition Monday night and ends with another unexpected entry to the lineup on July 9.

Because of the Fourth of July holiday, the anniversary week was supposed to start Tuesday. But when the Hacienda Brothers were in town last weekend, they told Zoo co-owner Pete Watters that they had July 4 off. So Watters invited them to return to Lincoln to play a 6 p.m. to 9 p.m. early show.

"We're starting the anniversary week early," Watters said. "We just want to make sure people know that we're having a show July 4."

The Haciendas were happy to make the drive from Wisconsin back to Lincoln. The Zoo Bar is the place where they played their first real shows, which were critical because they were on their way to South By Southwest 2004, said guitarist Dave Gonzalez. Their mix of country and '60s soul was an immediate hit in Lincoln and wowed the industry in Austin, setting them on their way to a record deal and touring the U.S. and Europe.

That loyalty to the Zoo can be seen in the anniversary week lineup that includes acts that have literally been playing Lincoln's best-known music venue for decades. Located at 136 N. 14th St., the Zoo remains one of the longest-running roots music clubs in the country.

Tuesday night, the show will be headlined by the Bastard Sons of Johnny Cash, the San Diego alternative country outfit that got the blessing from the Man in Black to use his name. The BSJC have a new record coming out and will be pushing those songs. Also on the schedule is Canada's Jack Semple, a Juno Award-winning guitarist who plays R&B and soul and by Lincoln's rockabilly sensation The Mezcal Brothers. Tickets for Tuesday's show, which runs from 6 p.m. to close, are $12 in advance, $15 day of show.

Wednesday is ladies night, with blues belter Lady Bianca headlining a bill that also features Renee Austin, an impressive Minnesota-based guitarist and singer, and Lincoln's own diva Annette Murell opening the show. Wednesday's show also runs from 6 p.m. to close and tickets are $12 in advance, $15 day of show.

Thursday brings former Zoo owner Larry Boehmer back to the club he ran for nearly 30 years. Boehmer now plays bass in the Tablerockers, taking the band name with him from Lincoln to his new home in Arkansas. That trio also includes another former Lincolnite, guitarist "Baby" Jason Davis. The Thursday night bill will be topped by Lawrence, Kan., R&B pianist Kelley Hunt, who's been a Zoo regular for decades. Opening the show will be the Blues Messengers. Thursday's show is from 6 p.m. to close, tickets are $15 in advance, $20, day of show.

Next Friday marks the return of a pair of blues guitarists who have been playing the Zoo for years. Jimmy Thackery made his first Lincoln appearances in the legendary Washington, D.C., blues band The Nighthawks before striking out on his own. He's now paired with Louisiana's Tab Benoit in a group they call The Whiskey Store Show. The show will start at 5 p.m., the Zoo's traditional FAC, with the Tijuana Gigolos starting things off. Lincoln bluesman Kris Lager and his band will play before Thackery and Benoit take the stage. Tickets are $15 in advance, $20 day of show.

The anniversary week wraps up on July 9 with a show that starts at 4 p.m. and offers something for all roots music aficionados.

On the bill are Lincoln's Charlie Burton and the Dorothy Lynch Mob, who entertain with countrified rock 'n' roll, Forty Twenty, the popular local country band, and the Darlings. The announced headliner is Mike Morgan and the Crawl, who'll bring the Texas blues back to the Zoo.

Somewhere in that lineup will be the Zoo's other new addition to the week. Los Super Vatos is a new band put together by Grammy winners Bubba Hernandez of Brave Combo and David De La Garza of La Mafia.

Here's how Los Super Vatos, which takes its name from the Chicano answer to Superman, describes itself on its Website:

"Los Super Vatos are not gangsters, but rather a band of dudes, or vatos, interested in performing music that includes genres within their culture. Such as, cumbias, rancheras, huapangos, boleros, and even a polka or waltz here and there. All these styles performed with a simmering, cooked with grease, Tex-Mex, R&B energy right out of a Spanglish cookbook."

Tickets for Saturday's show are $12 in advance, $15 day of show.
