The album, produced by Brendan O'Brien, features contributions from drummers Josh Freese and Joey Waronker, in addition to Ian Peres on keyboards. It reached number 17 on the Australian Albums Chart, number 25 in the UK, and number 71 in the US. Lead single "Victorious" registered at number 26 on the Billboard Mainstream Rock chart. Wolfmother promoted Victorious on the Gypsy Caravan Tour, which featured Alex Carapetis on drums. In July 2016, the group supported Guns N' Roses at two US dates on the Not in This Lifetime... Tour. They later returned for shows in Australia and New Zealand in early 2017. 2017–present: Single releases, Slipstream and Rock'n'Roll Baby Following the conclusion of the Victorious touring cycle, Hamish Rosser returned to Wolfmother. In March 2017, Stockdale released a self-produced song called "Special Lady", which he recorded on a laptop using the program GarageBand and only a vocal microphone. This was followed in November by the single "Freedom Is Mine", recorded and produced at Stockdale's home studio in Byron Bay, and "Happy Wolfmothers Day" in May 2018. Peres left in early 2018 after nine years with the band, committing to tour dates with Xavier Rudd instead. Stockdale and Rosser have performed with multiple touring line-ups of the group since Peres' departure: in April 2018 with Dave Atkins on rhythm guitar and Jake Bennett on bass, from May with Brad Heald on bass and Lachy Doley on keyboards, and later in the year with Katie McGurl in place of Doley. Bobby Poulton began playing bass and keyboards in October 2018 and is now the current session player in the band. In September 2018, Stockdale released his second solo album, Slipstream, which he promoted on a short concert tour. In April 2019, Stockdale began recording material for a fifth Wolfmother album at Dave Grohl's Studio 606 in Northridge, Los Angeles. This album, titled Rock'n'Roll Baby, wound up being released on 29 December 2019. On 24 October 2020, Stockdale performed "Joker & the Thief" at the 2020 AFL Grand Final.
