Winterglow: the special light quality that arises in winter when sunlight falls on snow. It is intense, clear, almost supernatural.
Malachi 4:2: "But for you who fear my name, the sun of righteousness shall rise with healing in its wings." In the Hebrew original: shemesh tzdaqah (שֶׁמֶשׁ צְדָקָה), "sun of righteousness".
Yeshua was often identified by the early church as shemesh tzdaqah. The sun that rises in spiritual winter. Mike's track is sound-becoming of this sun reality.
Mike's instrumental track carries the glow. It is not aggressively bright, it is warm-glowing. Like real winter sunlight. Mike's sound carries this English light reality.
