The qualities that won Rant a Herald Angel at the Edinburgh Fringe last month ooze from this debut album. Shetland sisters Jenna and Bethany Reid and Highlanders Lauren MacColl and Sarah-Jane Summers are among Scotland's leading fiddlers, and in forming Rant they have brought a string quartet's thinking to their arrangements of tunes that span Gaelic song melodies and pipe airs as well as such fiddle repertoire staples as strathspeys, jigs and reels. With no rhythm section, they propel themselves using muscular energy, subtle harmonies, pizzicato phrasing and thoughtful counter melodies. The sum effect is gorgeous. MacColl's East Church, dedicated to the scene of their first gig and this recording, has an almost harmonium-like presence as its delicate, graceful pattern unfolds and the Lenzie Lassies set's segue from bouncy jig to dark intrigue to uplifting melody with Beatles-esque coda is brilliantly realised. By turns atmospheric, soulful and joyous, this is music that never overplays its hand but revels in the richness of its creators' imaginations and talents.
