Just a Little Lovin’ - Shelby Lynne
Duende- Bozzio Levin Stevens
Bubbles- Yosi Horikawa
Some good ones already mentioned. A few odd ones that I used over the years. Pink Floyd Dogs
Depeche Mode Personal Jesus acoustic version
John Hiatt Feels Like Rain
Any drums recorded in the front hallway at Headly Grange . The best sound not recorded by John Bonham may be can’t get enough from bad Company’s debut record
