BOERNE, Texas. Four times a year, Rudi Harst and The Rudiments go underground to mark the turning of the seasons, and on Saturday, December 19, 2026, 7 PM, the band returns to the Queen's Throne Room at Cave Without A Name for Winter Solstice: Rudi & the Rudiments, a holiday concert for the longest night of the year. They have played the cave's solstices and equinoxes since 2002.
This is a band evening. Rudi's own page describes The Rudiments as seasoned San Antonio players with long histories on stages and in studios, a sound that blends ancient and contemporary music with folk warmth, rock memory, rhythmic precision and spiritual curiosity. At the Fall Equinox concert on September 19, the ensemble filled the cave as eight, with sitar, accordion, bass, hand drums and a drum kit gathered around Rudi's acoustic guitar.
Rudi leads from the center as singer, songwriter and bandleader, on vocals, acoustic guitar, Native American flute, dulcimer, harmonica and Tibetan bowls. The program pairs contemporary arrangements of traditional carols with original acoustic music, in a limestone room the venue prizes for its natural acoustics. As at every one of these cave concerts, part of the evening is performed in complete darkness, where, as the band puts it, the room becomes less a venue than a shared instrument.
Rudi has made San Antonio his home since 1974, with more than fifty years onstage, ten original albums, the book Hurry Slowly and the solo musical Ready or Not. In 1992 he and his wife, Zet, cofounded Celebration Circle of San Antonio.

A few practical notes from the venue: the concert room is reached by 126 steps with handrails and eight landings, and the cave has no wheelchair access. The cave holds at 66 degrees year round, so bring a layer and shoes with good traction. Seating is open, only bottled water is allowed inside, and most concerts run about 90 minutes. The venue does not state an age policy.
Cave Without A Name is at 325 Kreutzberg Rd., Boerne, TX 78006. The event is also listed on Facebook at https://www.facebook.com/events/1035547942353656/.
