Let’s go for an all-music morning roundup today, shall we?

ONWARD AND UPWARD: You may have heard that Sarah Jaffe is, as the kids would say, blowing up. As the national media jumps on the bandwagon, inevitably each new writer to discover her music will mention her solid songwriting. So it’s a treat to watch this video, recorded at the offices of Relix magazine, in which Jaffe talks about the origins of some of her songs. It’s kind of a mini version of VH1’s Storytellers. She also plays some of the songs with the trusty Robert Gomez at her side.

THE LIMITS OF LIVE: When the reincarnated Lilith Fair started canceling shows in bunches – including a Dallas date – music-industry watchers took notice. On the surface, the all-day event seemed like a no-brainer, with major acts like Erykah Badu, Norah Jones and others grouped with up-and-comers. But Preston Jones says the days of the all-day festival may be numbered. As listeners discover their music through their social networks, fewer people are willing to sift through a day of live performances to find their next favorite artist. There’s definitely something to that, though it’s tough to say how much the down economy has played a role in sluggish ticket sales. (That certainly played a part in the DSO canceling Smokey Robinson’s show tonight.)  Though, as Jones points out, that’s actually been a help to smaller local venues, who can get away with charging much less for a show.

ETC.: If you’re headed out to KXT 91.7’s Barefoot at the Belmont series to see Doug Burr and Joe Pugg tonight, please note: the show has been moved to the Sons of Hermann Hall in anticipation of sloppy weather. … Another KXT-related show also goes down tonight as the namesake of The Paul Slavens Show plays songs from his new release, Alphabet Girls Vol. 1, tonight at Good Records. His fingers hit the keys at 8 p.m. Joel North of Sleep Whale opens as Northern at 8 p.m., followed by Slavens. (Click here to watch a recent video of Paul playing at Dan’s Silver Leaf.) … The Hold Steady play the Granada on Saturday night. Quick spoke with frontman Craig Finn to get a preview of the show.
