How many different ways can the Salsoul pie be sliced? In the past 18 months the pioneering disco label's back catalogue has been apportioned across 16 CDs and 45 vinyl singles. At least Salsoul 30th has a neat gimmick: 30 tracks selected by 30 DJs to mark the label's 30th anniversary. (Well, technically it's now the 31st, but let's not be pedantic.)

The compilers, stretching from François Kevorkian to the Scratch Perverts, are spoilt for choice. In a just world, the Salsoul Orchestra's Runaway and First Choice's Let No Man Put Asunder would be as well-known as Stayin' Alive. Salsoul aficionados will have good reason to grumble (what's the point in featuring Ten Percent's Double Exposure, the first ever 12-inch remix, if you only include the four-minute original version?) but everyone else, confronted with some of the most life-affirming music ever made, will be disinclined to quibble.
