San Francisco indie musician John Vanderslice is well-known for his exhaustive, comprehensive, and lengthy approach to recording music. Legend has it that Vanderslice spent 4,000 hours working on one album. But his latest studio effort called “White Wilderness,” a collaboration with the Magik*Magik Orchestra, was completed in just three days to the surprise of fans and music critics. Vanderslice is in North Carolina to perform at the 2nd annual Hopscotch Music Festival in Raleigh.
