A minor band from near Viterbo, Blocco Mentale only released an album, called Poa (a greek word written on the cover in greek letters, it means "grass") in 1973 and soon disappeared after a later single. As introduced by its title, the seven-track album deals with ecology, lyrics are about pollution, nature, flowers and green grass, sometime with a very naive language typical of the time. Musically the album has some very interesting moments, but veers toward pop at times.
