Call it post-punk, math-rock or some other highfalutin, hyphenated genre: Media Jeweler make complex, guitar-forward music with a brash experimental streak. Emphasizing gnarly riffs and jagged beats, the Los Angeles-based group’s largely instrumental tunes are elaborately composed with only bass, drums and dueling guitars. Often, each component seems to strike out on its own musical journey, only to find its way back to meld with the others. The result is a striking, occasionally dissonant tapestry that emphasizes structure and space. Catch Media Jeweler on Monday, July 9, at the Monkey House in Winooski. Locals Dead Island open.
