Leonid & Friends brings their meticulous tribute to the classic Chicago sound to the Westgate Las Vegas Resort & Casino. This Russia-based collective has built a devoted following by recreating the horn-driven rock and jazz fusion that defined Chicago's golden era with remarkable accuracy. The ensemble features a full horn section, multiple vocalists, and a tight rhythm section that captures everything from the soaring brass arrangements to the intricate keyboard work that made songs like "25 or 6 to 4" and "Saturday in the Park" into rock radio staples.

What started as YouTube videos recorded in a Moscow studio has evolved into a touring phenomenon, with the band's attention to detail and obvious love for the material winning over both casual fans and Chicago purists. The musicians don't just replicate the hits—they dive deep into the catalog, pulling out album tracks and extended jams that showcase the technical chops and improvisational spirit of the original band. At the Westgate, a venue with its own storied musical history, the group's layered arrangements and energy translate naturally to the live setting, where the interplay between horns, guitars, and vocals can really breathe.
