A band intuitively connected to great, homespun British pop, “Palo Santo” announces Years & Years’ ascension to the world stage, through an escapist futuristic fantasia created by Olly Alexander. A once-in-a-generation frontman who understands more than most his responsibility as a pop star, his personal leap forward in scope and ambition is reflected in the album’s colorful mix of collaborators, which range from Greg Kurstin, Julia Michaels and Justin Tranter to Steve Mac and Sarah Hudson.
