This concert at The Observatory in Santa Ana pairs veteran alternative rock band AFI with support from Mareux, KUMO 99, and Los Angeles psych‑rock trio L.A. Witch, creating a multi‑act evening that spans punk‑tinged rock, darkwave‑inflected synth, and garage/psych textures. The Observatory is a longtime Orange County music venue with a main room and the smaller Constellation Room, known for hosting compact indie and rock bills. The bill showcases a cross-section of contemporary alternative and underground acts for fans of immersive, guitar‑driven live shows.
