Brief Bio:  
Born as Symphonic Bliss to two classical music composers in Las Pegasus, Symph trained to be a musical prodigy from a young age. The extensive training prevented her from gaining her cutie mark until age 18. They inspired each other to pursue their own type of music, leading to them moving to Canterlot together at age 20. Though Vinyl eventually moved to Ponyville to be with her marefriend, the two kept in touch, with Symph continuing her Metal/Rock musical career.
 
Cutie Mark Story:  
In efforts to rebel from her strict parents, Symph had several coltfriends. One of which was a wannabe rocker, whom Bliss often played music with. One day he convinced Bliss to try his electric guitar. Doing so caused her to gain her cutie mark. Starting then, Bliss started to go by the name Symphonic Rage.
