DAVE: I mean, you’ve got the potential, but you’re sloppy. I need a clean roll on the toms but powerful, like Moon.
The toms refer to tom drums a cylindrical drum with no snares, named from the Anglo-Indian and Sinhala language of Sri Lanka, derived from thammattama, from the Tamil word thappu, a type of drum.
Referring to Keith Moon, previously discussed, drummer for The Who, and one of Lane’s drum heroes.
Dave and Lane have come up with a plan to keep their relationship a secret from their bandmates – Dave will put Lane down in public, patronise her, and insult her. Lane is totally into it, as she loves zany schemes and keeping secrets.
