LI'L CAP'N TRAVIS began like so many Austin bands, playing sloppy but earnest alt-country with semi-sober apathy, and their first two albums betrayed a band that had a lot more going for it. Their third, . . . IN ALL THEIR SPLENDOR (Glurp), might let a lot more people in on the secret. Gone is the low-fi production; instead, keyboards and steel guitars swirl. Some songs twang; others find a nostalgic psychedelic pop sound; a few even ring with Crazy Horse thunder. LCT boasts four members who both write and sing, which keeps things sounding fresh, but it's the wistful work of guitarist Christian Braafladt that anchors its sound. Here's a born storyteller; when he starts a song, you stick around to see where it's going.
