Black Flag ex-frontman Henry Rollins listed his bunker-like residence in Los Angeles recently. Rollins, a nearly ubiquitous cross-media presence and perhaps the prototypical ‘influencer’, is asking $3.895 million for the .43-acre, four-bedroom property.

Details of the 1991-built home that leap out as particularly suggestive of its present owner include the use of steel doors in the shared living area—they appear more impenetrable than invitational, and as an accent fit the tough, concrete-heavy 4,997 sq. ft. Mediterranean-and-modern-tinged residence very well. The 60-foot living room is a bright space with a freeing, open feel. Visual touches of the interiors include a mosaic tile kitchen backsplash, mid-toned plank hardwood floors, and perhaps some terrazzo.

The home’s more luxurious features include a bar area, a gym, a sauna and steam room, an outdoor terrace complex with a protective solid balustrade and a pergola, a guest bedroom with floor-to-ceiling bookshelves, and a recording booth. The master suite features a bath with a freestanding tub, as well as a lounge area and a creative workspace.
