In January 2012, Heir Apparent's original musicians (Gorle, Schwartz, and Peace) performed with Jeff Carrell on vocals at the Metal Assault II Festival[8] in Germany, with additional concerts in Athens and Thessaloniki Greece in celebration of the 25th anniversary of Graceful Inheritance.
In October 2015, Heir Apparent performed their first concert in Italy at the Play It Loud Festival[9] with vocalist Will Shaw and keyboardist Op Sakiya joining Gorle, Peace, and Schwartz.
