Gather as much information as you can about the performers prior to your review. If information does not come from an official source, contact the performer or their agent directly to confirm details.
Ask if you can have an opportunity to meet or speak to the performers before or after the show. It is not vital to interview performers for a review, but it can add a great deal to your article if you are able to.
Arrive at the venue in good time. If you have arranged press tickets, report to the appropriate person to collect them. Check your seats or standing point. It is important you have an unobstructed view of the stage. If this is not the case, contact the venue's management or press officer you have been dealing with and explain why it is important you have a clear view.
Keep notes throughout the performance. Invest in a "reviewer's pen," which has a small light attached so you can write notes even in the dark. Write down any key moments, events or quotes as they occur. If you are unsure about anything, note a question mark beside it so you know to check back with the performer or press officer later.
Pay attention to the rest of the audience. How are they reacting to the performance? While the review will necessarily be your own opinion, it is important to include details about the overall atmosphere and how others respond. Just because you enjoy or dislike something does not mean others will feel the same, and if there is a big discrepancy that is worth writing about.
Write your review as soon after the performance has finished as possible. Include basic details such as when and where the show took place, the name of the show, and any key performers. Double check you have all name spellings and other facts correct.
Write your overall opinion of the show. Keep in mind you should be basing your opinion on the type of performance, rather than your personal tastes. You may not usually enjoy hip hop or classical opera, but if you have agreed to review it, you should be able to evaluate the quality of a performance regardless of personal taste.
If the performance is to be repeated on other nights or in other venues, include details of these at the end of your review. Not all publications will include these, but it is useful to include them for those that do.
