Holy Sun Opera House at its core is soprano and drummer Krissy Barker with composer dl Salo. Along with a revolving cast of collaborators, singers and performers, they create emotionally engaging and haunting symphonic music embellished by electronics, heavy drums and synthesizers. The group has been described as “Opera Cult” and as one who would play at the Roadhouse in Twin Peaks. They draw influence from early Dead Can Dance, Fever Ray and Klaus Nomi.

The Holy Sun Opera House is the group's self-titled debut set for release in May 2026 on the label Hologram Opera. The self-produced album was conceptualized as a way to describe an obsessive mind with music and inspired by the recurring dreams of singer Krissy Barker. In it is a realm of shifting rooms, dilapidated houses and passages. These unsettled rooms and spaces pose a striking confrontation of fear and anxiety from deep within.

In its conception, The Holy Sun Opera House was written as a passage through these ethereal dreams and spaces. The song Latched On depicts the compulsive psyche as a draining physical entity attached. While Voice of Gob, Decrepit Mansion, and Room with the Rain observe and attempt to find acceptance in this conflict. The Passages I & II travel between the curtains to the unknown entity residing in The Attic, who looks inside the mind of the dreamer and determines she has no soul.

The album blends genres with electro, darkwave, and contemporary classical music. The ritualistic passages of the choir throughout the album are reminiscent of Wicker Man and 1970's mystic cults, praising the deities residing within the dream. The arrangement of synths, electronics, heavy drums and operatic singing lend itself to something uniquely memorable.
