NASHVILLE (AP) — Dan Auerbach of The Black Keys is so into the Netflix documentary series “Making a Murderer” he wrote a song about it. Auerbach has posted the song “Lake Superior” to the website of his other band, The Arcs. “Making A Murderer” is about the Wisconsin legal trials of Steven Avery and Brendan Dassey, who were convicted of killing a woman. The series suggests authorities planted evidence, but those involved in the case say the series omits crucial facts. Auerbach says the series is moving and disturbing, regardless of how you feel about the men. Auerbach says The Arcs put together the song in just a day and a half. Proceeds from the sale of the song will go to the Innocence Project, which uses DNA evidence to exonerate prisoners.
