Sister (In Solitude album)

The album averaged 78/100 on Metacritic which indicates "Generally favorable reviews." Andy O'Connor, writing for Pitchfork, gave the album 7.1/10, and was largely positive about the album. In particular, he praised the song 'Pallid Hands', writing that the song "brings a romanticism that hasn't been seen in metal in a while, and is the group's finest song to date. It recalls 70s Judas Priest's more bittersweet moments, a casualty of the group's success in the 80s, or a more serious stab at April Wine's “Sign of the Gypsy Queen”. In Solitude are a young band—Palm is the oldest member at 26—and for them to craft a song filled with weariness and whiskey-afflicted love is a stroke of “Old Man”-like brilliance." However, he was critical of the closing track, writing that "'Inmost Nigredo' clocks in at just over eight minutes, as opposed to the nearly 14 minutes of “On Burning Paths”, but it still languishes without bombast. This is an unfortunate betrayal of their songwriting prowess, which the album thrives on."

Erik Highter of PopMatters was positive about the album, awarding it an 8/10, concluding at the end of his review that "Sister is the sound of a band growing and coming into their own, drawing on disparate influences inside and outside the genre. They’ve taken Fate into their own hands and in the process made one of the best records of the year." Natalie Walschots of Exclaim! was likewise positive about the album, awarding it 7/10, writing that "Dark and syrupy in tone, with just the right amount of haze, as if from sacred smoke, Sister is a fine addition to the witchy, ritualistic hard rock that's leaving an ever-darker mark on aggressive music."
