In 2017, their third album was released by MINOS EMI UNIVERSAL entitled "Rise of Strings". They have dealt with all the styles of music, since their program, apart from their own works (Pontian casino, Piratical, Life and Truth of a Politician, etc.), includes innovative music compositions based on original works by Bach, Vivaldi, Hatzidakis, Iron Maiden, Queen, Vamvakaris and Tsitsanis, but with a rock and a pop twist.  In many of their pieces, they combine the Greek musical tradition with the wider western music. In their live performances, the various music and play styles alternate with a variety of sound colors and loud crust drum snapshots, creating a dynastic string-based atmosphere.
