"Vurdering: B-" - "In Sparks, Imogen Heap returns with her fourth solo album, three years in the making and possibly her most adventurous offering yet. With her track record for innovation in music, and especially for marrying human emotion with leading-edge technology beyond gimmickry, Heap sets her own bar high. On successive listens, it's difficult not to be impressed with the results; there is such silkiness to Heap's music that it can initially drape itself over you with its sheer conviviality. It's a challenge to listen intently, to absorb the myriad strands she weaves together, so repeat exposure is both necessary and ultimately rewarding".
