METALCASTER

METALCASTER has been publishing since 2020, and across the 6 years since has built a catalogue of 66 episodes. That works out to roughly 40 hours of audio in total. Releases follow a roughly quarterly cadence, with the show now in its 16th season.

Episodes typically run thirty-five to sixty minutes — most land between 30 min and 40 min — and the run-time is fairly consistent across the catalogue. None of the episodes are flagged explicit by the publisher. It is catalogued as a ES-language Music show.

The show is actively publishing — the most recent episode landed 5 days ago, with 37 episodes already out so far this year. The busiest year was 2026, with 37 episodes published. Published by Mariano Martín.
