Members of Spiritualized, the Jesus & Mary Chain and Gang Gang Dance make cameos on Sian Alice Group's 2008 debut, 59.59. As might be expected from such a guest list, the London band often embraces the swirling, undulating density of shoegaze — although its songs are more than just a chain of expensive effects pedals strung together. Manic Gypsy rhythms, '70s electric jazz and chamber pop crop up as points of departure, while lead singer Sian Alice Ahern makes her mark with an ethereal, spectral voice. It's an arresting, ambitious debut energized by its extremes: The warm, burbling amorphousness of "As the Morning Light" feeds into the clanging thump of "Way Down to Heaven." Brooklyn noise annihilators A Place to Bury Strangers headline the show.
