In 1986, Marco Bosco's percussive arsenal was unique and extremely peculiar, containing chizanzhi, caxixis, purrinhola, requo-requo, shequeres, berimbaus and lingo drum, among other instruments. This fusion of acoustic and synthetic, promoted by some Brazilian artists in the 80's and celebrated worldwide, still brings memories to the percussionist. For him, the arrival of those electronic gadgets "was the best thing that happened on the planet". This reissue includes a reproduction of the original artwork, new testimonies by Marco Bosco and a a long article signed by Bento Araujo, author of the series of books "Lindo Sonho Delirante", which investigates audacious and fearless music produced in the Brazilian underground.
