This is a remix of the 86’s Doctor Who theme, composed by Dominic Glynn for “The Trial of a Time Lord”. I tried getting as close as I could to as many of the elements as I could, and I think I succeeded pretty well.
Point of interest: The TV version of the theme sounds different from Glynn’s master recording, because the TV aired theme had different equalizing, some filters added, and it is slightly detuned.
