No new Polish music showcase is complete this summer without a performance from the über-talented songstress Julia Marcell. She composes her own songs and plays her own instruments - piano, violin and guitar - underpinning it all with a fresh electronic rhythms. Her voice has been compared to a blend of Björk Kate Bush, Regina Spektor, Lykke Li and Joanna Newsom - but she shakes up all comparisons by wavering between breathy and ethereal to strong and smoky.
