This is the first work performed by Stevie Wonder to create a soundtrack, the documentary "The Secret Life of Plants", based on a book of the same name of Wallon Green. As the producer of the documentary -Michael Braun- and the sound engineer -Gary Olazabal- were describing to him every detail and sequence of the documentary, Stevie Wonder was transforming it into sound sensations. It Was recorded between February and April 1979 and released in late October. It's a double album that comes three years after the huge success of the previous album and that is not well received by critics, the album was largely instrumental and very unorthodox in the business, giving more priority to compositional and creative aspect. Despite this, and that the documentary was not shown to the general public got a platinum record and No. 4 on the charts R&B and Pop in the USA
The journey through the secret life of plants employing unusual combinations synthesizer including the first use of a digital synthesizer sampling -Computer Music Melodian- is one of the first digital recordings. On this album Stevie Wonder mixed sounds from oriental folklore, African music, classical music, jazz, or ambiental music, crediting one of the first recordings New Age. The album cover was chosen by Rolling Stone in 1991 in a list showing the best top 100 classic covers. The technical mastery of Stevie Wonder, is perfectly merged with the suggestive mysticism radiating documentary content, creating a fascinating testament to the emotional and spiritual symbiosis that may exist between plants and man. An album of worship for many people, getting his digital recordings were influences for the new digital sound that will come a little later in the music of the 80s.
