Rebecca Jean Rossi (a.k.a Krystalmath) is an NYC based music producer, composer, multi-instrumentalist and singer. 

While studying classical piano performance at the Eastman School of Music, she discovered her passion for electronic music and composition and began focusing on music production. 

Between 2007-2012 she worked on crafting her individual sound as a producer. During this time she wrote and sang for an indie rock band that toured the US and most of Europe, and also produced a single in collaboration with the late but great Prodigy of Mobb Deep. 

Finally in 2015, she wrote, produced, and released her first album under the name Krystalmath- with her first single “Same Mistake” hitting Spotify’s New Music Friday playlist and then the Global Viral 50, peaking in 15th place and receiving over 200,000 plays within a couple of weeks.

The entire Krystalmath catalog was picked up in 2016 to be featured on In-Store playlists by stores like Forever 21, Gap, etc. by PlayNetwork, Inc.

Always interested in a wide variety of musical genres, she is currently collaborating with various artists on a pop EP and will also be releasing an additional EP of instrumental piano compositions in 2020.
