Emeralds — musicians John Elliott, Steve Hauschildt, and Mark McGuire — emerged from the rust-pocked, post-millennial Midwest drone / noise scene seemingly unable or uninterested in keeping up with themselves. Their proliferation of material was intimidating; mountains of improvised, home-recorded music were released on limited-edition tapes, CD-Rs, and split LPs. There is and was a sense that the Ohio trio was after something beyond physical mediums. By 2008, their sprawling live sets were a known can't-miss at any underground experimental event. Tiny Mix Tapes reviewed that year's appearance at No Fun Fest: "No one's sawtooths, sines, and other various waveforms were so beautifully sculpted and beamed out into the Plejades as Emeralds'." These basement dwellers were shaping meditative, psychedelic, arpeggiated electronic music in the veins of German kosmische forebears like Ash Ra Tempel, Klaus Schulze, and Tangerine Dream. Made primarily with synthesizers and guitar, Emeralds' music possessed the same astral psyche with a home-crafted punk edge, a distant descendant of that pioneering era, and a bridge to someplace new, someplace scorched.

Released on Aaron Dilloway's (Wolf Eyes, etc.) Hanson imprint, Solar Bridge was the first Emeralds album to receive any kind of proper distribution and represents the first attempt to archivally preserve their fluid craft. The first of an inimitable five-LP run before the band dissolved in 2013, Solar Bridge is a moment of glistening primacy that boots up a catalog and legacy that the heads still grapple with. Emeralds begin to make sense of it in the fall of 2022 with a remastered Solar Bridge LP release on Ghostly International.
