Big fan of those early Little Feat records. Strange to think about it now, but I even saw them open for the Who on the last tour before they lost Moon. Fun band. Sounds like you probably already have most of the well known stuff by their contemporaries like The Allman Brothers, but what about this one?
Everybody on this board probably has at least one recording with David Lindley in the credits on guitar or any number of stringed instruments or arranging since he has worked with almost everyone from the Bangles and Bread to Bob Dylan and Ben Harper, and even appears on the Holly Cole
Don't Smoke In Bed album I saw mentioned in another recent thread. His own album with his El Raxo-X band is great, and features some very good musicians including some vocals by his buddy Jackson Brown, who he helped tremendously shaping the sound of those early albums with his guitar playing and arrangement skills.
Something from more modern times that I've probably mentioned a few times here, not really like Little Feat, but still I think something you may like, is Paul K. & the Weathermen
Love Is A Gas. From 1997, and a little reminiscent of another guy that uses only a "K" for his last name on record, Tonio K. And his sound also has ties to Lou Reed and the Velvet Underground (Moe Tucker produced and played some drums along with Wilco's Glenn Kotche) and PK dedicates it to David Ruffin [Temptations] and Sterling Morrison [Velvet Underground], and comparisons have been drawn to Merle Haggard and especially Townes Van Zandt by others, and there's some of the Replacements, and also some of his musical brother, Greg Dulli from the Afghan Whigs. But K's songwriting and voice and guitar playing are still the big attractions. This is really a beautiful album of finely crafted songs with lots of guitars - highly recommended. Readily available on the used market, but also still available in both CD and inexpensive vinyl from Alias Records.
