The Shekhawati region of Rajasthan is famed for its ornate havelis. One such is Alsisar Mahal, a heritage building that&rsquos now a heritage hotel. In mid-December, this mini-palace became the throbbing, pulsing venue for the Magnetic Fields Festival 2014 &ndash a rather unusual choice, you may think, as the fest was celebrating the best of the international underground music scene, far removed from the colourful folk tunes of Rajasthan. But for that very reason, because of that contrast, the ambience was special.
