While Sigur Rós has been fading into an “indefinite hiatus,” the group’s frontman Jón Birgisson went and made the best record of his career. Retaining some of his band’s atmospheric elements, Go sports poppier, more energetic tunes sung primarily in English rather than vowel-heavy “language” Hopelandic, but still in that ethereal falsetto. The record’s enchanting surges of string orchestration feel stunningly cinematic, and that picturesque quality will be embodied in an epic staging created by London-based 59 Productions. Dubbed “a cross between film, art installation, theatre performance and live gig,” the show projects a natural world in which animals are brought to life and film meets lighting and prop. And if it does justice to Jónsi’s imaginative quality as it claims, the performance will be as monumental as the music. With Death Vessel. NICK FELDMAN
