Marimba music

"Gong" of Pierre Moerlene.
Also check out Ed Mann often played with Frank Zappa.

Here are a few favorites sort of in descending order (most marimba dominated to least):

Submedia/Suffocating City
Brad Dutz/Railroads
Double Image/Double Image
Jack West/Big Ideas
Reinhard Flatiscler/Megadrums
Uzva/Tammikuinen Tammela
Hasse Bruniusson/Flying Food Circus
Daniel Denis/Les Eaux Troubles (Coeur de Boef is great!!).
Budi Siebert/Hmmmm... (vinyl is best on this one)
Christer Bothen/The Spirit of Milvus Milvus (exc. b. clarinet too)
Jerry Granelli/Another Place
Bob Moses/When Elephants Dream of Music
James Emery/Standing on a Whale fishing for minnows
Anthony Davis/Episteme
Ralph Peterson/The Reclamation Project
Henry Threadgill/Everybodys Mouth's a Book
NRG Ensemble/Calling all Mothers
Also, Capt. Beefheart/ Doc at the Radar Stn. and Shiny Beast (Bat Chain Puller) have some interesting marimba on them.

Thanks. I have heard of very few of those artists.
