The success of The Curse the Cross & the Lion opened an opportunity to travel to Bulgaria to debut a new symphonic piece for an orchestra in Burgas in the summer of 2013. Upon returning to the US, Felix began composing a choral symphony sung in Classical Latin titled Neon Heaven. The US debut took place in Austin, TX in March 2015 during SXSW by the Texas Choral Consort. The European debut subsequently followed in Denmark at the International SPOT Festival with additional performances in Portugal and Mongolia.
In 2016, Felix was featured on PBS and nominated for a Lonestar Emmy for work on his 6-Piano project in which he restored six pianos for a concert featuring two new pieces. After the concert, Felix donated the pianos to schools in lower income neighborhoods in Austin.
In addition to his recent work with orchestra, Felix served as an official music ambassador for the US in China and composed music for a series of PSA’s for an international campaign by LIVESTRONG to raise cancer awareness in China and Mexico. In late in 2014, Felix reformed his band, The Noise Revival Orchestra, for a tour in Asia highlighted by festival dates in Japan and Taiwan where TNRO performed for crowds of 35,000 and 50,000!
