According to a statement from Aerosmith, Kramer is sitting out "so he can focus his full attention on his family during these uncertain times." He will again be replaced by longtime drum tech John Douglas, who sat in for Kramer during his last absences back in 2020.
While Kramer's absence is described as a "temporary leave," he missed most of the shows in the band's initial 'Deuces Are Wild' residency.
Kramer reportedly injured his shoulder during the initial run of shows in 2019 but didn't rush to rejoin his band. The situation began deteriorating publicly when Aerosmith began preparing for the Grammy awards and its MusiCares Person of the Year honors in 2020.
After several months out of the loop, Kramer wanted to perform again with his fellow co-founders for the Recording Academy accolades. His bandmates, however, weren't convinced the he was physically ready for the gigs and repeatedly denied him his return. Kramer even tried suing for the right to get back onstage, but a judge denied his request.
Despite how ugly the situation got, Kramer still attended both events alongside his bandmates. He eventually rejoined Aerosmith in Vegas in February of 2020.
This week, Aerosmith announced two dozen Las Vegas shows, spread out across this year.
