Entropy formed in 1990, from an idea by Michele Antonio Coppola (drums) and AL Laghi (vocals). Shortly after, the two founders of the band were joined by the third historical member of the band, Marco Campassi (bass) and after a few auditions, the band found its stability with Alfredo Acampa (rhythm guitar, lead). Entropy quickly became one of the main bands of the "second wave of neapolitan metal", at the beginning of the 90s, and in particular the shows at the Hard Rock Cafè in Naples, soon became unmissable happenings among the Neapolitan metal fans of the time. After some records and lineup changes they still manage to bring new music and live dates until now!
