The trio reunited in 2009 and their sixth studio album, "Neighborhoods", consisting of their characteristic sound and the band member's different music tastes, was released in 2011 through Interscope to modest success and generally positive reviews, reaching number two on the "Billboard" 200. The band departed Interscope the next year. In November 2012, the group would record the "Dogs Eating Dogs" EP, released independently a month after. Tension would grew between the trio as new material was planned to be recorded but due to DeLonge's side projects kept delaying dates, he would quit the band afterwards. Hoppus and Barker recruited Alkaline Trio frontman Matt Skiba to fill in for DeLonge to perform two club shows and a slot at the Musink Tattoo Convention &amp; Music Festival in March 2015. After legal battles with DeLonge were worked out, Skiba, who returned to Alkaline Trio for a string of dates and the release of his side project the Sekrets, rejoined Blink-182 as an official member. Between January and March 2016, the new line-up consisting of Hoppus, Barker and Skiba recorded "California", produced by John Feldmann for its release in July on independent service BMG to mixed to positive reviews. The album included, for a first time, outside songwriters, the likes of Patrick Stump of Fall Out Boy. It also marked their second number-one album in over 15 years, thus becoming their first to top the charts in the United Kingdom and receiving a Grammy nomination for the Best Rock Album award. After touring in support of the album, recording process began developing for the following record.
