I had several chances to get to talk to Chris Walla of Death Cab for Cutie whenever he shopped at the cool grocery store where I used to work. We mostly talked about our shared love of Sloan and 'Favourite Worst Nightmare', but one of the last times we talked I asked him what new band he was most excited about and he said it was Yellow Ostrich. The bold Brooklyn band recently replaced one founding member with two new members as their fifth full-length ‘Cosmos’ invokes Carl Sagan’s (and I guess now, Neil DeGrasse Tyson's) way of staying amazed at the world.
