Palm plays rock music backwards. Eve Alpert and Kasra Kurt’s guitars occupy themselves most often with the pace-keeping work typical of a rhythm section. Meanwhile, Gerasimos Livitsanos’ bass and Hugo Stanley’s drums perform commentary and reportage from their deeply embedded positions at the front. The band is firmly attached to the physicality of rock, but not as much its tone; their instruments tend to sound like any number of things at any given time. None of the members of Palm are formally trained on their instruments. The band formed in 2011 at college in Upstate New York, when high school friends Eve and Kasra met Gerasimos and Hugo. Their first album, Trading Basics, was written in Hudson, NY, a riverside outpost where the group could clarify its intentions outside the direct influence of nearby cultural capitals. That year, the members of Palm relocated to Philadelphia, where they continue to live only a few blocks apart from one another. This proximity has facilitated a level of collaboration necessary for a sound so slippery to remain in the firm grasp of its players. On Shadow Expert, they made use of the steady hand granted by a tireless touring schedule, cutting their songs to efficiencies of pop confection without sacrificing the avant-adventurism at the center. With Rock Island (2018), Palm excuses the company of these myriad influences with a sly brush of a hand, ushering the listener into a new domain, thrillingly strange for all its familiarity.
