"Equinox", Gianni Marchetti's 1977 twin album of "Solstitium", released in a handful of promo copies by RCA in their renowned "Original Cast" series, takes us on a journey through the author's groovier and wilder temperament, feeling as fresh and surprising today as the day it was made, offering immediate understanding of the reasons why it has remained one of his most sought after - and virtually impossible to find - titles over the decades.

RIYL: Piero Umiliani, Sandro Brugnolini, Stefano Torossi

The limited release as part of RCA's "Original Cast" series only increased its mystique, making it a coveted piece among collectors and connoisseurs. The album's distinctive character lies in its spontaneous, freewheeling approach, which contrasts with the more polished productions of the era. It's a perfect example of Marchetti's unique vision, where each track seems to evolve organically, offering both intricate musicianship and a sense of unrestrained creativity.
