Maybe we can thank Red Iguana for Los Lobos adding another night to their visit to Salt Lake this weekend.

Whatever the reason, that the band added a two-show set at The State Room to their sold-out co-headline appearance at Red Butte Garden with husband-wife blues-rockers The Tedeschi-Trucks Band.

And whenever Los Lobos takes the stage, you can count on a performance crackling with electricity.

Best known for their cover of Richie Valen's "La Bamba" for the movie of the same name, Los Lobos has spent more than four decades cranking out a brand of music that honors their East L.A. roots, infused with roots, country, punk — the whole spectrum — while relentlessly touring with a live show jammed with soul and energy.

This time, the 2016 Rock and Roll Hall of Fame nominees and four-time Grammy Award-winners are touring behind their 2015 release, "Gates of Gold," their first studio recording in five years, an overlooked gem that received critical praise and, true to form, spans the breadth of their musical influences.

"We're a Mexican American band, and no word describes America like immigrant," says Louie Perez, the lead songwriter for the band. "Most of us are children of immigrants, so it's perhaps natural that the songs we create celebrate America in this way."

"Gates of Gold" features tracks like the straight-ahead blues jam "I Believed You So," the traditional Spanish-language "Poquito Para Aqui," the Jimi Hendrix-ish "Too Small Heart," and dark and moving "Song Or The Sun."

If you're catching the Red Butte show on Sunday, don't count on hearing much from the new album. Based on the set lists from the earlier shows on the Wheels of Soul tour, Los Lobos plays a shortened set — usually featuring a couple covers in the eight or nine song set — sharing stage time with Tedeschi-Trucks and the North Mississippi Allstars.

Susan Tedeschi and Derek Trucks have become a staple of the Red Butte season, bringing back their driving blues-rock sounds to the venue for the fourth straight year and the eighth time since the concert series began.

This time, the band has a new album, "Let Me Get By," their first since 2013 that features Trucks' dazzling guitar work and Tedeschi's wrenchingly earnest vocals.

To get the full Los Lobos experience, however, The State Room show Saturday night will be the one to see, with the band scheduled to play two sets that, by the end, will probably mean needing to replace the roof on the venue.

Tickets are still available for The State Room show (the Red Butte show has sold out) and are $65. —
