I could find no information about Carl W. Landahl (1908-1961), but I think he taught at Augsburg College in Minnesota. That would make sense, as these two Chorale Preludes were published by Augsburg Publishing House in 1963.
Both of the chorales, "O darkest woe" and "Blessed Jesus, at Thy Word" are really like "hymn elaborations," rather than true chorale preludes.
I've played them both in a manner that respects their dignity and simple beauty.
