The structure, which was erected in place of an old electrical supply warehouse on 24th and R streets, was designed by Sacramento’s Ellis Architects and the Bay Area’s CAW Architects. With one wall adorned with a towering mural of a roving horse, by Sacramento artist Cheyenne Randall, and a modern auburn facade, the building — whose namesake references the electrical “channels” of its warehouse days and Sacramento’s converging rivers — is an unexpected addition to the mostly residential southeast corner of Midtown Sacramento’s grid.

Although the throng of mostly 30- to 50-somethings was enthusiastic about the chillwave indie rockers that night, Channel 24’s roster serves a broad audience, including younger fans with a proclivity for country music. The venue’s opening night on April 24 featured Tucker Wetmore, attracting a sold-out crowd outfitted in cowboy boots and wide-brimmed hats.

For fans who have long faced a 90-mile trek for mid-level acts, Channel 24 fills a longstanding void. While smaller indie bands regularly play the 530-capacity nightclub Harlow’s and megastars hit the more than 17,500-seat Golden 1 Center, the state’s capital has lacked a home for artists who sit comfortably mid-lineup on a Coachella poster.
