The 2004 Boxing Day tsunami resulted in the WaveAid fund-raising concert held in January 2005 : Silverchair performed to help raise funds for aid organisations working in disaster affected areas . As a result of WaveAid the band decided to resume working together . Gillies explained the band 's reunion as due to a special " chemistry " between band members , telling '' The Sydney Morning Herald '' , " It only took us 15 years , but recently we 've realised , ' We 've really got something special and we should just go for it . ' " After performing at Wave Aid , Silverchair reunited and by late 2005 began preparations for their next studio album , '' Young Modern '' . Johns had written about 50 songs during the hiatus for a possible solo album or other project but decided to use them for Silverchair . In 2006 , after five weeks practice the group demoed tracks in the Hunter Region , and then recorded at Los Angeles ' Seedy Underbelly Studios with Launay as producer . Parks again arranged orchestral tracks for the band – they travelled to Prague to record with the Czech Philharmonic Orchestra . The group also used Mac , Luke Steele ( The Sleepy Jackson ) and Julian Hamilton ( The Presets , The Dissociatives ) – Hamilton also co-wrote songs with Johns . Silverchair self-funded the album 's production to ease the pressures faced previously when working with a record label
