Kutless' most beloved songs erase the line separating Christian alt-rock from contemporary worship music. The 2005 single “Strong Tower” is huge with grungy power chords like crashing waves and praise harmonies reaching skyward. On the flipside, “What Faith Can Do” showcases their melodic gifts with gleaming keys that walk gently alongside Jon Micah Sumrall's aching meditations on the Lord's miraculousness. The driving “Bring It On” is another powerhouse, capturing Kutless' ability to communicate spiritual awe by layering guitars, strings and drums into a big, sublime celebration.
