If four records counts as short lived, of course, I'm with Msarty, and the great
Uncle Tupelo
I'd add
Nadine
three records, with their first, "Downtown Saturday," an alt country classic.
Also in the vicinity, with 3 or 4 records,
is
Whiskeytown
another alt country classic. Never bought into Ryan Adams after he left the band. Maybe Caitlin Cary was the driving force.
