'Purity' is the third excellent CD by 2001 Rocky Mountain Harmony Sweeps finalists, all-male quintet T Minus 5, an 8-song collection. Six of the tunes are Gospel hymns: 'Because I Have Been Given Much,' 'Precious Lord, Take My Hand,' 'Jesus, the Very Thought of Thee,' 'Once in Royal David's City,' 'I Need Thee Every Hour' and 'A Poor Wayfaring Man of Grief' (which is lightly piano accompanied) The final two cuts are the folk tune 'Shenandoah' and 'The Star Spangled Banner.' Rich harmonies and deep feeling are present in each of these inspirational, beautiful selections.
