Linda Sussman’s “Remember Dorothy” feels like a quiet anthem for today’s complex landscape. It’s not loud, but it doesn’t need to be. The song, rooted in simple acoustic slide guitar and Sussman’s unvarnished vocals, speaks to the necessity of courage in the face of societal pressures. There’s a directness in her delivery that brings to mind the classic folk-blues era, where the music’s power lay in its message, not its embellishments.
