What conductors do before a performance is their own decision. They may do as they wish. Some conductors will listen to the music that will be performed, others will avoid the music being performed as much as possible. During the performance, the conductor will conduct all the pieces just as they were rehearsed. After the performance, they usually celebrate by drinking.
Most performers I have known prepare before; review and evaluate the performance afterwards. I have known seasoned concert performers who said that they never practice any more and that after a performance they simply forget about whatever may have happened. That is all a matter of individual style. [If you are referring to specific behavior before and after, then I have known people who hold a reception both before and after and those who stay in seclusion before and after. Again, it's a matter of individual preference.]
DRUGS!
The conductor.
The conductor is the one who conducts the orchestra, managing speed, dynamics and instructing each instrumental section when to enter, and so forth.
Role of the Conductor during Performance The role of the conductor in an orchestra is mainly to keep everyone together, especially on tempo changes. Role of the Conductor during Rehearsal During rehearsals, the conductor is responsible for determining how the music will be interpreted and for noticing and correcting any errors in how the musicians are performing. Other Roles of the Conductor Usually, the conductor also chooses the repertoire of the orchestra for each season.
The conductor stands in the middle and conducts the orchestra. One of his/her principal responsibilities is to give the performers the signals at the correct time. During rehearsals, a conductor usually reshapes a composition for orchestra beyond the composer's instructions.
They usually are pianists, but there ir no obligation, you can study conducting even if you are not a technically great performer, bur you need to hace very clear the ideas of performance and very high knowledge of the instrument of the orchestra

A conductor can make sure that everyone plays at the same beat. The conductor is usually a learned scholar of certain composers works and will offer his ideas and interpretations to the members of the orchestra during rehearsals on what he thinks the composer intended the piece to sound like. Besides keeping time, there is also the matter of phrasing, tempo changes, and dynamic changes.
The conductor typically follows a score during a performance.
If you are referring to the London Symphony Orchestra (LSO), the answer is that it had several principal conductors during that period: Previn, Abbado, Tilson Thomas, and Davis. If you are referring to another symphony orchestra located in London (it has more than one!) please say which one.
Most chamber orchestras have a conductor. Sometimes the concertmaster takes the position of "leader" and does the conducting from her/his seated position. Specifically, the Orpheus Chamber Orchestra works without a conductor. They work out the tempi and other features during rehearsal.
No, not solely. The conductor also gives cues for entrances, listens for any problems during practice, such as wrong notes, intonation issues, and any other problems, etc. In general, the conductor is in charge of running the orchestra, including other duties such as choosing music.
Really, it depends on what you're thinking of. Instrumentation, you're looking at a full symphony orchestra, with harp, etc. If you're thinking about the fireworks etc, it really depends on what the conductor and choreographer wants at the time. I've seen a performance of it in the Royal Albert Hall (London) where they had the Royal Welsh Guard standing in the gods with rifles. There was also lighting effects, smoke machines and coloured explosives. But I also saw a performance when I was away, where they only had bangs, no particular effects.
