MARCO D'ANDREA is the guitarist and founder of the hard rock/metal band PLANETHARD, with whom he released 4 albums. Following the excellent response obtained with his first solo album "EVERYTHING I HAVE TO SAY", he continued to record the second one named "Opera Rock". The second album was inspired during the first lockdown of 2020 when Marco gathered (from a distance) a large group of Italian rock and metal guitarists and singers, to record for charity the italian national anthem in a different key: Mameli Rock. In this album, a reinterpretation in a rock key of classical and lyrical pieces whereas Marco's electric guitar is the main element, albeit often accompanied by very good musicians. Marco D'Andrea, with Opera Rock wanted to launch a trait d'union between the world of rock and metal music of which he has always been a representative (we recall the multiple participation with Planethard at Gods of Metal, and the support slots at Gotthard and Scorpions, just to name a couple) and the teachings given by his diploma in classical guitar at the Conservatory.
