In the pantheon of composers who have worked on Star Trek, none are more prolific than Dennis McCarthy, who has been working with the franchise since the debut episode of The Next Generation to the final episode of Enterprise. Of course, whether you think that's a good thing or bad depends on your opinion of his music.
With the rather large caveat that Mr. McCarthy's composing abilities were limited by the franchise’s producers and production capabilities, who placed less emphasis on bold thematic music in favor of reusable "mood" and "atmospheric" cues, I must admit that, on the whole, I've not been impressed. I know it's not the composer's fault, and that I'm probably unfairly comparing his work to the more grandiose Star Trek film scores, but it's hard to wrap my head around the largely ambient, mood-setting scoring. a similar complaint I have regarding the bulk of Christopher Franke's Babylon 5 music. Maybe it's just a general limitation of writing music for television.
However, I recently listened to McCarthy's score for the premiere episode of Deep Space Nine (Emissary) and was quite surprised at its musical complexity. Though I've never been a big fan of the lumbering syncopation of the show's main title, I can’t help but get caught up in its a magnificent crescendo. It’s a perfect segue into each episode.
While McCarthy's music for the Borg Battle at Wolf 359 is not nearly as menacing or action-packed as Ron Jones' from The Best of Both Worlds, it too ends on a dramatic note that works, both by itself and on screen as we see Sisko's escape pod leave the Saratoga just before its destruction.
The score, from there, delves into the backdrop zone until the track Cucumbers in Space, an oddly-named piece of futuristic head-bopping source music. The score reaches a highlight on Into the Wormhole which evokes Jerry Goldsmith's exquisite V'Ger flyover music from the first motion picture. Later, during Reconciliation there's a cue that's reminiscent of one of my favorite passages from the third movement of Mahler's sixth symphony.
All in all, I found the score to Emissary to be an unexpected treat.
