Music: Little Boots, Sicknote@Cabaret Voltaire, Edinburgh

**** Xenomania, Cathy Dennis and other purveyors of production-line pop better watch out. Because 24-year-old Victoria Hesketh, pictured, aka Little Boots, has absorbed the back catalogues of Kylie, Girls Aloud and Christina Aguilera in the way little girls learn dance routines. What's more, her own brand of electro-pop was developed not in expensive studios, but on retro-analogue equipment and performed as a one-gal band.
