Italian soundtracks from the late '60s to mid '70s are practically a genre to themselves and have long been a treasure trove for those who seek unique jazzy psychedelic beats. In the early '90s, both the retro-exotica crowd and the rare groove DJs re-discovered Italian soundtrack music thus giving it a big boost in popularity. The Black Cat label responded to this renewed interest with its 'Loungissima' series that re-packaged a variety of Italian soundtracks in attractive vinyl LP collections. 'The Psych-Jazzy-Beat Of I Marc 4', features the music of one of the top recording quartets of Italian soundtracks, I Marc 4. The members of this quartet all came from a jazz background and originally grouped together in the mid-'60s with the purpose of supporting various high profile vocalists. In the late '60s they moved on to being soundtrack composers whose instrumental works would then be collected and released on LPs. Psychedelic rock, soul jazz, brassy Herb Alpert style numbers, spacey exotic lounge music, goofy country funk, proto-progressive rock are the easily recognizable genres coexisting in this retrospective of one of the most hidden treasures of the Italian psych-jazz scene.
