Acts of Faith felt like an appropriate name for Sault’s debut live show; in terms of shots in the dark, paying £99 to see an enigmatic mystery collective perform in a former branch of IKEA surely ranks up there pretty highly.When this special, one-off gig was first announced, there was a fair amount of (understandable) grumbling; even if the price-tag served as some sort of statement after the band surprise-dropping five downloadable albums entirely for free last year, it’s still an awful lot of money.
