An aerial view of one of Slipknot’s many packed performances
USA - Slipknot are known for some of the most intense live shows on some of the biggest stages on the planet. The Grammy Award-winning, and multi-platinum-selling group has spent much of the past two years on their ongoing Knotfest Roadshow, which recently wrapped up its third post-pandemic tour sweep of North America.
Sound reinforcement provider Eighth Day Sound, a Clair Global company, has been supplying the tour legs with a robust K Series loudspeaker package from L-Acoustics.
Wrangling the PA for the group are FOH engineer Bob Strakele and system engineer Brian Sankus, who have been deploying ever-evolving loudspeaker setups as the band has moved from sheds to arenas and then back to sheds. “At the beginning of 2022, we were going from amphitheatres into arenas, so on each side, we flew 14 K1 over four K2 for mains, 12 K1-SB subs, and 12 K2 for out-fills,” Sankus describes.
“In order to adapt and be quick for the rolling stage, we did six carts of three KS28 subs, in cardioid, with an A10 Focus on the top of each for front-fill. This was able to stay strapped together, use the least amount of cable, and be struck at ease. We also had six A15 Wide for auxiliary-fills.”
For the most recent leg, which returned to the sheds, Strakele and Sankus opted to rely solely on K2 for mains instead of the more traditional K1. “On this latest run, we carried a total of 56 K2 and 20 K1-SB, plus our normal 18 KS28, six A10 Focus, and four A15 Wide,” he continues. “To save truck space, we circuited out hangs as three and stuck to 18 LA12X amplified controllers per side, which kept us very flexible in the sheds and two arenas that we did.”
“Slipknot's music is chaotic, and it’s a lot to manage,” Strakele chimes in. He took over the band’s house mix several years ago, following the passing of FOH engineer Dave ‘Shirt’ Nichols, who originally specified L-Acoustics for the group’s touring. “Much of the band’s material is very fast, with hectic elements. When you have three drummers all playing at once, plus sub-samples and a DJ on top of it, low-end management is key.
“This kind of music in an arena would be a total mess if we didn’t have a proper sub deployment. I like the system’s low end to be tight, fast, and out of the way really quickly. I’m not a fan of ‘fluffy’ subs with this band. That being said, most of the work is done by the K1-SB in the air while the KS28 on the ground are nicely picking up the slack at the barricade.”
To ensure that the sound reinforcement system for every show was bespoke to the geometry of each venue, Sankus relied daily on L-Acoustics Soundvision software. “Being a former production manager, I keep the rest of the show elements in mind the whole time, and sight lines are a major concern of mine. The last thing I want is for a band member or attendee to be staring at the front or back of a box for two hours,” he shares. “I’ve absolutely been loving the Autosolver tools, which give me a great stepping-stone to move quickly toward the right setup. They take a lot of the guesswork out and give me more time to dive in and finesse what I want.”
Sankus concludes: “Night after night, we achieved what we set out to, which was to provide the same tonal energy from the front row to the last.”
