Rush performed its final concert with drummer Neil Peart at the Forum in Los Angeles, California, in 2015 [1].

This performance serves as the definitive end of the trio's touring era. Because the band ceased live operations following the R40 tour, the event represents the final time Alex Lifeson, Geddy Lee, and Neil Peart shared a stage before Peart died in 2020 [1].

The concert concluded the R40 Live tour [2]. The tour was designed as a celebration of the band's four-decade history, bringing the group back to their roots while showcasing their evolution as musicians. The Los Angeles show functioned as the closing chapter for a lineup that remained unchanged for most of the band's existence.

Neil Peart, the band's lyricist and drummer, played a central role in the group's complex arrangements. His departure from the stage in 2015 [1] preceded his death five years later in 2020 [1]. The loss of Peart effectively ended any possibility of future Rush tours, as the remaining members maintained that the band could not exist without its original trio.

Lifeson and Lee have since reflected on the legacy of the R40 tour and the specific weight of that final Los Angeles performance [1]. The Forum, a historic venue in the U.S., provided the backdrop for the final notes of the band's live career [1].

While the band had played numerous shows across the globe throughout the R40 tour, the finality of the Los Angeles date was not fully realized until after Peart's death [1]. The event remains a focal point for fans of the progressive rock group, marking the conclusion of a partnership that spanned decades.

The final concert of Rush's R40 Live tour took place at the Forum in Los Angeles.

The conclusion of the R40 tour in 2015 transitioned from a scheduled tour end to a permanent historical marker following Neil Peart's death in 2020. Because Rush operated as a tight-knit trio with irreplaceable roles, the finality of the Los Angeles show signifies the end of one of the most stable and influential lineups in rock history.
