The Residents, the anonymous art-rock collective, are staging a live reworking of their 1979 album Eskimo in Honolulu for two nights — a treat for fans of experimental performance.

• The band has kept its members' identities hidden for more than 50 years, preferring to be known for the work rather than the faces.
• A longtime spokesperson handles publicity because the group itself refuses to speak publicly.
• They are less a conventional band than a collective of musicians, filmmakers, and performance artists working across media.
• Eskimo, their most successful record, grew out of a deliberate push away from rock toward something no one could compare to anything else.
• Shows run tonight and tomorrow night, starting around 7 p.m.

Outlook: Audiences should expect a theatrical, unpredictable show rather than a straight concert.
