Modest Mouse has removed guitarist Simon O'Connor from its upcoming tour following accusations that he sent inappropriate messages to a teenage fan on social media. The indie rock band enlisted Seth Jabour of Les Savy Fav as O'Connor's replacement.

The decision comes after allegations surfaced regarding O'Connor's conduct with a minor online. Modest Mouse, led by frontman Isaac Brock, has not issued a detailed public statement but confirmed the personnel change to the touring lineup. This marks another instance of a touring musician facing removal due to misconduct allegations in the streaming age, where social media interactions can quickly escalate into public accountability moments.

O'Connor joined Modest Mouse in 2020, appearing on the band's 2021 album "The Lonesome Crowded West" reissue tour and subsequent performances. His departure disrupts the band's live setup on what would have been a significant touring cycle.

Jabour brings considerable experience to the role. As guitarist and vocalist for the New York-based experimental rock outfit Les Savy Fav, Jabour has spent decades navigating avant-garde indie rock circles. His addition suggests Modest Mouse intends to maintain the tour's momentum while addressing the allegations head-on through roster changes rather than cancellation.

The incident reflects ongoing conversations within the music industry about online safety and accountability. Unlike decades past when touring musician behavior could remain obscured, contemporary social media trails create permanent records of interactions. Bands now face immediate pressure to respond when members face credible allegations.

Modest Mouse's catalog, built on Brock's distinctive compositional voice and rotating lineup of collaborators, has always accommodated personnel changes. The band's live presentations depend less on locked-in chemistry than on Brock's creative direction, making a mid-tour substitution more feasible than it would be for tighter ensembles.

Jabour's involvement signals that the tour will continue, preserving fan experiences while signaling the band's position on the allegations against O'Connor.
