The Modern Sound Quartet represents one of the most treasured, yet least documented, outfits in the history of Italian library music. An exceptional studio band of session musicians with a formidable groove, they released only a handful of albums under this name in the second half of the 1970s. However, their sound indelibly shaped dozens of "invisible" soundtracks, often without ever receiving an official credit on the back sleeve. This boxset celebrates their funkiest side—an irresistible combination of incandescent drum breaks, tight grooves, and high-intensity fusion passages—bringing together some of the most sought-after tracks from legendary LPs like Erbe Selvatiche (1977), Floreama (1977), Horoscope (1978), and I Tarocchi (1980). The selection also delves further back to the roots of their sound, including two powerhouse tracks from Pop-Paraphrenia (1973), a project where Oscar Rocchi—backed by a young, lethal Tullio De Piscopo on drums—sowed many seeds that would fully blossom in the subsequent Modern Sound Quartet output. Available in a limited worldwide edition (500 copies), enriched by iconic 70s-style artwork conceived and designed by Eric Adrian Lee.
