The album inspired positive reviews upon release, and was praised for its even more psychedelic and space rock feel as well as higher production values compared to their debut The Weirding. The heavy metal review at About.com stated "San Diego maestros Astra craft expansive suites that hearken back to the original root of mind-expanding, unrestrained and genuinely progressive rock. Rich with hallucinogenic and hypnotic promise, and slathered in layers of vintage, billowing instrumentation, the band's stunning sophomore album, The Black Chord, expertly evokes the spirit, tone and vision of '70s cosmic prog."[1]Ytsejam.com described the album as "combining the dark grooves of Sabbath, with the improvisational tangents of King Crimson, the moods of the early eras of both Yes and Genesis, as well as hints of space rock from Hawkwind… the use of crunched guitars, brass [sic], woodwinds, a variety of Mellotron sounds and Moog/analog synths, syncopatedjazz drumming, and growling bass… yield honest results as everything sounds organic…."[4] According to Sound Colour Vibration, there is a "depth and reality that a lot of progressive rock bands fail to obtain."[5]
