Yo La Tengo's new album, "Popular Songs," recorded in early 2009 in Hoboken, N.J., and Nashville with longtime producer Roger Mountenot, isn't out until Sept. 8. But just in time for its summer tour of minor league ballparks opening for Wilco, the New Jersey trio has made the album's first single available for download on Matador's Matablog (matadorrecords .com). "Periodically Double or Triple" might not break any new ground, but the band certainly seems to be having a grand old time. The group splices together the backbeat to "Taxman," colors the groove with some fuzzy hockey-rink organ that sounds like Booker T. sitting in with the late-period Turtles and creates its sunniest single to date.
