Wunderhorse is the alias of British musician Jacob Slater. His is a feral, romantic, visceral, chaotic and enchanting cacophony of sound that contradicts itself with each sleight of hand and change of chord. A rare, raw and assured talent, Wunderhorse is barely a song down, but that first number is the urgent fever-dream of Teal, tumbling with the brakes off. Belligerent and unblinking. Arthouse Indie-rock, but without the connotations. Here’s to a precocious new British songwriter.
