Another great season of Waterfront Wednesday has come and gone and it’s time again to move indoors for WFPK’s free music series, as the first Winter Wednesday, featuring Daniel Martin Moore and David Wax Museum, takes place this Wednesday. Kentucky-born singer-songwriter Daniel Martin Moore — who has worked with Joan Shelley, Ben Sollee and Jim James — plays a style of breezy folk that subtly branches in all different directions. David Wax Museum’s style lives in the same genre, but delves into the more exploratory side of things.
