The Easybeats
Vanda and Young from The Easybeats produced AC/DC's early stuff with Bon Scott who was their original singer which really rocked compared to their later stuff which was just heavy and leaden IMHO. I have an Easybeats complete US. and UK. singles CD with 22 songs on it, I also like their earler stuff on first listening, but I haven't listened to it enough to have a good opinion.
