This EP, called "Regeneration", is born by the collaboration between two italian independent artists: the acoustic/pop songwriter Giorgio Croci and Alex Lupi, leader and producer of the Air Signs trilogy. Mixing their different composition styles, Croci and Lupi tell a "musical tale" in 4 songs/stories, representing the 4 seasons and a journey through the cycle of time and the human spirit. Everything starts with "Forever", the melancholic autumn wind that throws away the man from his land, while he desires the deep love of his companion. The journey continues through the huge and cold universe described in "Beyond the universe", where the man reaches for the heart of the space inside the winter: a sun of consciousness. The third chapter of the EP is the landing on Earth in full spring, with the song "Coming Home". The conclusion of the project is the immense heat of the summer, recalled by the symphonic composition "Sometimes", inspired to the hope to have a new start.
