Wonder Days

Wonder Days is the tenth studio album by Thunder, released in February 2015. It was recorded in late 2014 at Rockfield Studios in Monmouth, Wales, and produced by lead guitarist Luke Morley, who wrote everything on it apart from "Black Water", a co-write with Saint Jude vocalist Lynne Jackaman. It was the band's first record for earMusic and their first studio album since Bang! in 2008.

It is a comeback record, arriving after the band's second break-up in 2009 and a handful of reunion shows between 2011 and 2014. Ben Matthews, recovering from head and neck cancer for most of 2014, is absent from much of it. The public welcomed it warmly: it entered the UK chart at number 9, their first top ten album since Behind Closed Doors in 1995, and topped the UK Rock & Metal Albums Chart. "Wonder Days", "When the Music Played" and "Resurrection Day" were the singles.
