The white guys and gals in the 1900s recall another ambitious Chicago rock band, the Fiery Furnaces, but without the proggy convolutions and dissonant keyboard embellishments. Rather, the 1900s generate a smoother brand of psych pop with more winsome melodies and amiable textures while avoiding obvious homage to their '60s forebears. The fact that the 1900s once served as a backing band for Belle & Sebastian member Stevie Jackson hints at their smart tunefulness—and at Jackson's fine taste in watermelon-sugary songcraft.
