Invisible, from 1974, is the first studio album by the Argentine rock band Invisible and the seventh in which Luis Alberto Spinetta has a decisive participation. The band, made up of Spinetta himself (vocals and guitar), Pomo Lorenzo (drums) and Machi Rufino (bass), had proposed to make a different sound from that which predominated in national and international rock at that time, playing without distortion and looking for a clearer and random sound. 1 2 The cover art, like the illustrations that accompany the lyrics of the songs on the inner sleeve, are drawings by the Dutch plastic artist M.C. Escher, in whose work Spinetta found inspiration, 3 as well as in the original indigenous cultures. 4 In the first vinyl edition of 1974, the album was organized as a double album, made up of an LP and a single titled La Llave del Mandala. The sleeve contained both records and had all the lyrics of the album and the single, each of them headed by an image, four of them works by Escher. The 1985 reissue of the album omitted both the bonus single and the lyrics to both songs on the back cover. The 1990s CD reissue of the album included the two songs from the single as bonus tracks, along with the other two singles released by the band. It has been included at #65 among the 100 best Argentine rock albums by Rolling Stone magazine.5 Notably, none of its songs appear on any list of Spinetta's best songs.6 At the Spinetta y las Bandas Eternas mega-recital organized by Luis Alberto Spine
