Tony reappeared in the metal scene around 2006 as Atheist reunited for some live dates and also took part in Patrick Mameli's project C-187 on the album "Collision". As Patrick announced the reformation of Pestilence in 2008 Tony also joined, this time as a full member. He played on Pestilence - Resurrection Macabre and the accompanying Tour but left the band in October 2009 because of his other projects. Tony will be on a new Atheist album and his latin pop band Area 305 also scheduled a new album this year.
