Does anyone knows these people :

- "Antimatter" (might be also known as Xopher Davidson)
- Gregory Lenczycki 
- Naut Humon
- Maryanne Amacher

???

Any information besides the occasional internet brief bio's (wich I
allready have) is welcome !!

These people belong to my top list of sonic artists and I can't find any
useful info on them,
especially about Maryanne Amacher and Xopher Davidson.
