Mark Nelson's Pan•American project has been very quiet over the last several years, as he has been focusing instead on his Anjou collaboration with former Labradford bandmate Robert Donne. With A Son, however, Nelson returns to his solo work in bold and unexpected fashion (by his own quiet and understated standards, at least). In fact, there is very little that stylistically recalls Nelson's post-rock or smoky ambient-dub past at all here, though his aesthetic generally remains a very moody and slow-moving one. At the heart of A Son lies a handful of hushed vocal pieces that capture Nelson's vision at its most stripped-down, direct, and intimate. Those pieces are occasionally quite wonderful, making this release a fitful creative breakthrough of sorts. The rest of the album is not quite as striking, but the blend of songs, sleepily lovely ambient work, and hammered dulcimer pieces add up to pleasantly gentle and dreamlike whole.
