Secret Machines, one of the most exciting new bands out there, will be featured tonight on NPR's All Songs Considered Live Concerts series. The show will be tonight at the 9:30 Club in Washington D.C., and will be webcast live. The shows then are archived for future listening. Past shows available for streaming include Lucinda Williams, the Decemberists, Interpol and Wilco. All of the shows are at the 9:30 Club.

Also on tonight's bill is Kings of Leon, a band that seems to have fizzled a bit. After the breathtaking debut, Youth and Young Manhood, the band stumbled considerably on its flat follow up Aha Shake Heartbreak. TV appearances around the time of that first disc showed a band not in full mastery of its instruments. Here's hoping tonight shows signs of practice.

Inexplicably, Secret Machines is opening the show, scheduled to go on about 8:45 p.m. CDT, followed by Kings of Leon an hour later.
