Best short-lived band?

Mad Season.

Elastic

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.

John

Guns and Roses (for best of 80's rock band and in the original "Appetite for Destruction" member line up).

Spirt
Mountain

Pish in your Hazen!!

Joy of Cooking

The Blues Project.

IMO. Regards,
-- Al

Zephyr

Derek & The Dominoes.

Traveling Wilburys - With Roy Orbison before he died.

Rockpile wasn't bad.

Plain Brown Rappers

Have 'The Young Bloods' been mentioned yet? Remember Get Together?

The Youngbloods (one word) were around for a number of years. Remember Darkness, Darkness? Sunlight?, Both were big FM radio hits in 1969 from Elephant Mountain, a truly terrific album.

Little Village
Con Brio
Blind Faith

The Bubble Puppy, remember the song; "Hot smoke and sasafrass"

Loverboy and Saga.

Sex Pistols. 1 album and 1 bootleg. Still snarling after all these years.
