Wrest is from Douglas, but they're all over the place musically.
"We go from pop punk to alternative to metal, and a little death core," says the band's 17-year-old singer and guitarist, Andre Olivas.
Fittingly, his personal-favorite band is Linkin Park, the alt-rock, nu-metal and rap-rock group.
Rehearsing for the Battle of the Bands has been keeping Olivas, a junior, and the rest of the band from Douglas High School - seniors Victor Lugo, 19, a guitarist; drummer Joseph Morales, 19; and 18-year-old bassist Carlos Olivas - busy.
Andre Olivas says they've practiced nearly every week and more recently, "maybe even five days a week, at least three days a week."
Their songwriting method is a mixture of the occasional band member bringing in lyrics and music, and a collaboration between members at rehearsals.
Olivas says he has written all the lyrics and the guitar parts for three songs. "But, usually, one of the guitarists will come up with a riff and we'll just work off of that and all get together and throw in ideas, bass and drum parts."
The band is a tight group, and not just musically.
Bassist Carlos Olivas is Andre's cousin, but Andre says they all might as well be related - the loyalty and friendship in Wrest are as important as the music.
That helps overcome their musical differences. For instance, Andre Olivas says Carlos is into cumbias and Michael Jackson, Victor's tastes range from White Snake and Van Halen to Ben Folds, and Joe is a fan of Tool and A Day to Remember.
Olivas sets the band's agenda, picking times to practice and taking care of other band business.
They recently set up a show at Club 3000, a Douglas bar that also rents out space for quinceañeras, weddings and parties. But Olivas said the big freeze broke a pipe that flooded the roof and caused the ceiling to cave in. So, they did a show at a friend's house and each made about $16 to go toward the cost of coming to Tucson.
He said only about five friends drove the 120 miles from Douglas for the warm-up show at Club Congress last month. He's hoping for more for the finals on Friday but not expecting it.
Other than the Battle of the Bands warm-up and competition, the band's musical experience out of Douglas has been a show at the Rock in Tucson. They also come up to attend occasional concerts.
Olivas says he's known for several years that he wants to take music as far as he can.
"I had been playing trumpet in sixth grade. I started out playing drums around eighth grade, four years ago," Olivas says. "Then I saw Disturbed playing at the Rialto and said, 'I want to do what he is doing. I want to play on that stage.' "
He was already working on his singing and played trumpet in the school jazz band. But after seeing Disturbed, he started working on guitar.
"We want to make it a career," Olivas said and then added, as if a high school counselor were sitting on one shoulder and whispering to him: "But, we always have to have a backup plan. I want to go to college."
One thing is for certain, Olivas says: "We look at it as we're family and friends first. If the band should ever break up, we should stay friends. Band second, and friends first."
