Vashti Bunyan’s recent comeback has been pretty low-key, but there are worse fates: at least her story has been happier than those of Nick Drake and Sandy Denny, whose music her exquisite, slightly fey Brit folk occasionally resembles. Her 1970 debut, Just Another Diamond Day, was produced by the well-connected Joe Boyd, featured members of Fairport Convention and the Incredible String Band, and was arranged by Robert Kirby, who worked on Drake’s first two albums. There’s a 35-year gap between her debut and Lookaftering (DiCristina), but the sound is similar; fans Devendra Banhart and Joanna Newsom lend a hand, and Kirby’s back too, pitching in on trumpet and French horn. Last year Bunyan told Perfect Sound Forever that during her years away from the music scene she kept busy raising a family and never thought of returning–she’d given away all her copies of her first record–but on Lookaftering she sounds like she never stopped for a moment.
