Mitski Miyawaki, a singer and songwriter known for both candid lyrics and a catchy yet volatile version of indie rock, makes her Frost Amphitheater debut this September. Her latest album, The Land Is Inhospitable and So Are We, feels like a love that’s haunting the land. “This is my most American album,” Mitski says about her seventh record, and the music feels like a profound act of witnessing this country, in all of its private sorrows and painful contradictions. In this album, which is sonically Mitski’s most expansive, epic, and wise, the songs seem to be introducing wounds and then actively healing them. The album is full of the ache of the grown-up, seemingly mundane heartbreaks and joys that are often unsung but feel enormous.
