Seals & Crofts - Diamond Girl: Quadio (Blu-ray Audio Disc) * * *

Seals & Crofts' 1973 Album Diamond Girl: Quadio on Blu-ray Audio Disc. Transferred from the Original Half-Inch Four-Channel Masters. Blu-ray with 192/24 Resolution Quadraphonic & Hi-Res Stereo Mixes.

Diamond Girl (1973) found Jimmy Seals and Dash Crofts leaning into a more polished sound, expanding their folk-pop roots with the driving "Standin' on a Mountain Top" and atmospheric "Nine Houses." The album went Top 10, introducing two major hits, the jazz-inflected title track (#6) and its melodic follow-up "We May Never Pass This Way (Again)" (#21). Even when they're rocking out on "It's Gonna Come Down (On You)," the duo's signature two-part harmonies remain the center of attention.

Quadraphonic sound, or 4.0 surround sound, utilizes four audio channels connected to four speakers positioned at the corners of a listening space. The multi-tracked audio is mixed dimensional, immersing the listener in an expansive soundscape.
