Details: Stone Age Is Back, the third solo album from singer-songwriter and poet Caleb Nichols is a fascinating and urgent addition to his growing catalog. Like a PhD dissertation in contemporary indie rock and alt-folk, the album pulls from disparate strands of Nichols' universe to form an amalgam of queer ecology, rustic punk, existential folk, frenetic indie pop, spoken word, experimental jazz, and Neil Young-esque shredding.
