Gregory Smith is a musician in the same league of these other musicians also:
Sol Kaplan, George Duning, Gerald Fried, George Romanis, Ron Jones, Don Davis, John Debney, Richard Bellis, and Paul Baillargeon. Other musicians are Dennis McCarthy and Jay Chattaway... And perhaps Star Trek: Armada One by Danny Pelfry and Danny Baker. More of this music must be added to Star Trek Online also.
Many of these musicians are on Star Trek in the few episodes and video games that they got to compose any thing... and musicians that are not from Star Trek, with a few are on Space Age Pop, many from that time period... such as: Paul Horn, Henry Mancini, Edward Bilous, Jeff Alexander, Don Barto, Patrick Williams, Jack Elliott, Allyn Ferguson, Eugene Poddany, Walter Greene, Bill Lava, Doug Goodwin, Rob Walsh, Don McGinnis, Joe Siracusa, Carlos Brandt, Dean Elliott, Elliott Lawrence, Ed Bogas, Hoyt Curtain, Bob Sakuma, Masahito Maruyama, Yuji Ohno, Maury Laws, Bernard Hoffer, Jerry Martin, Pinocchio In Outer Space, Halloween Is Grinch Night, Judge Mathis, Soul Train, and numerous Game Show musicians. Also perhaps some of the King Of The Hill musicians such as John Frizzell and John O'Connor. And also Lance Rubin and Roger Neill.
I became familiar with Gregory Smith since I watched Star Trek, In Living Colour since 1964. Star Trek has been about at least occasionally mystical music for example from George Duning. The first six movies also, with Leonard Rosenman particularly is another of many examples. And then for The Next Generation they hired a secondary musician Ron Jones. Rick Berman hated the music and eventually fired him and killed the sound track for Star Trek and others. The spiritual successor of Ron Jones is Paul Baillargeon, who worked for Rick Berman on The Big Blue Marble. This is the only reason why Rick Berman ever hired Paul, as well as Don Davis, John Debney, and Gregory Smith. Other musicians are Sol Kaplan and Richard Bellis and George Romanis.
Rick Berman is very tone deaf; he seems to prefer the music of David Bell, and Velton Ray Bunch. The regular musicians Dennis McCarthy and Jay Chattaway can compose music of various qualities, but seem to prefer to make different melodies, instead of being forced to use Wall Paper.
Paul Baillargeon was probably hired to make six episodes per year, three for Deep Space Nine, and three for Voyager. But Paul Baillargeon only made at most 5 episodes each year... and that is how Gregory Smith made three episodes for Deep Space Nine, one each year. These episodes sound the same as Paul Baillargeon.
I do not know why Greogry Smith stopped after those three episodes; Perhaps after 1999, there was only one programme made instead of two. When they make multiple long 26+ episode each programmes again (after a 20 year gap?!) It is going to exhaust Jeff Russo and Michael Giacchino. And it is unacceptable to have them recycle the same few tracks.
I was hoping that Enterprise lasted for 7 seasons, and if they focused on Space Battles instead of Trip and Porthos, it would have. And then I would be able to enjoy even more episodes of Paul Baillargeon.
Even if Paul Baillargeon will not come out of retirement, John Debney and Gregory Smith are still active. Gregory Smith even has a web site.
They are making this programme Strange New Worlds which is finally about Captain Pike. I hope they are able to use the grey walls and dark blue stained glass ceilings that made the 1964 film so futuristic. Hopefully they can recreate the magic that the original actors did... Every time (even in Fan Recreations such as Phase II New Voyages and Continues) the next actor to be Kirk ends up much more like Archer instead. Perhaps they will also remember that they had mystical music such as from George Duning and also from The Paradise Syndrome by Gerald Fried.
Ron Jones would frequently recreate this type of music.
And also Paul Bailargeon.
An example of the mystical, perhaps somber at times, music by Paul Baillargeon is from episode Blink Of An Eye. Another good example is Chosen Realm.
To hear samples of Gregory Smith's music, it is very easy since there are only three Star Trek episodes. That is The Assignment, with the very talented and under used actors Colm Meaney and Rosalind Chao. One of the scenes in the middle of the episode Keiko (Chao's character) jumps off the ledge. Now some episode about a Bajoran named Yassim and her "Evil Must Be Opposed." protest before jumping is from a David Bell episode. The music played during that scene is 110+% inappropriate noise. But in The Assignment, the music is completely different... actually good.
The next episode is Honor Among Thieves. He has a special assignment again, to discover who is stealing weapons. He befriends the espionage person, and there is very grim, tense, and somber music playing. This music, just as in The Assignment, matches the style and quality of Paul Baillargeon.
The final Gregory Smith episode (that I for the longest time mistaken it for a Paul Baillargeon episode) is Field Of Fire. This is when Ezri Dax investigates impossible crimes on the Space Station.
I do not know why these musicians have not returned to Star Trek, but Gregory Smith has a web site. He might be convinced to return the moment that the Star Trek producers are able to hire numerous musicians and give them their own episodes.
