Little know fact: my good friend produced the Strand of Oaks album HEAL. He said they sent the tape of the opening song (Goshen 97) to J Mascis to overdub a guitar lead, and told J to record leads for the intro and between two verses.
J sent back three takes. All he did was start ripping in the intro and played through the whole song. So they just used the bits that worked best.
But it’s a really good album.
EDIT–oddly enough, on wikipedia, my friend is listed as the producer of Pope KIlldragon. Weird. He did HEAL, and is listed in the album credits as such. Maybe he did both. Hmm.
Further edit–apparently he is listed in the credits with another person as producer, but wiki only has the other guy.
