In August 2013, during Evanescence's hiatus, guitarist Troy McLawhorn was interviewed by Munib Nawaz from Radio1 FM 91 Pakistan.
The interview lasted for more than 47 minutes, but at 26:40 Troy told us that before Evanescence's tour manager (Andrew Weiss) called him to fill in for John LeCompt who left in 2007, he was doing a construction work in Miami.
He said that he couldn't find any job in Atlanta, so he became a construction worker to build a mall in Miami. When Evanescence called him, he was very excited.
He had to learn 20+ songs from Evanescence in a short time, but since he grew up playing in bands where he played cover songs, he didn't really have a hard time doing it.
