Tangomorfosis is the first symphonic tango-rock opera ever written.

This work for symphony orchestra, rhythm section, bandoneon, glockenspiel and four singers (three sopranos and one tenor) features 14 songs that tell a story through four characters: the Tanguero, the Devil, Love and the Night. (See synopsis).

The overall production and compositions are by Martín Delgado (San Telmo Lounge), while the lyrics were written by acclaimed Rosario-born musician Adrián Abonizio (Trova Rosarina).
