The first 10 pages show a two-page photo spread for each day of the concert, but at different stages of the concert.
Then there are four pages per member spread throughout the photobook. It also includes a profile of each member.
There are also four to six pages for each unit stage. I'm happy they included photos of Infinite Band, despite not including the performance on the DVD.
One section is dedicated to rehearsal the day before the first concert. XXX
The remainder of the pages are filled with gorgeous pictures of the rehearsal, behind-the-scenes, and on stage. The last two pages are for the credits.
The concert itself is really amazing. It's a very small venue, holding just a few thousand fans, and it feels like you can connect with Infinite more because of the closeness. Also the summer theme has such a relaxing feel, which matches with Infinite performing some of their songs acoustically (such as "That Year's Summer," "Amazing," "I Like You," and "Wings"). It's just nice seeing a different type of concert than Infinite's past giant and powerful concerts. The VCRs also fit the summer vacation theme, with Infinite having fun at a summer house, having an indoor campfire, and playing games like the Truth Game and Rolling Paper (this is not paper for cigarettes...it's where you pass a piece of paper around, writing messages about a specific person). Another VCR is like a chat room, where L gives advice to the other members. As for solo and unit performances, Infinite H performed "Without You" before its official release,
The second disc also contains a "Special Live Cam," which is like a high quality fancam of each member. Oddly enough and disappointingly, they didn't include one of Myungsoo. The songs for each member are "I Like You" (Sunggyu), "Without You" (Dongwoo), "Be Mine" (Woohyun), "She's Back" (Hoya), "The Chaser" (Sungyeol), and "Entrust" (Sungjong). It's fun seeing how the different members perform in various stages; like with Sunggyu, you could see how much emotion he put into his lines, and how he was having fun lip singing the other members' lines.
The third disc contains three special features. The first one is the "Making Film: Concert Marking," which is 27 minutes long and shows Infinite throughout the seven days prior to the concert. It was cool seeing the various stages of practicing for the concert, such as rearranging the songs, practicing the choreography, and actually rehearsing at the venue. They also had a long segment of Infinite Band, which was really nice. The second feature is "Making Film: Concert D-Day," which is 40 minutes long and shows Infinite during the five days of the concert series. It showed them arriving at the venue, rehearsing on the stage, as well as actual footage from each concert day. I liked how they also showed a bit of Infinite Band here, though they didn't provide the audio of it. It was also cool seeing Infinite wearing different costumes, like sometimes they wore black outfits instead of the feathered ones used in the concert DVD. The last day also included Infinite's celebration afterward, which included other celebrities like Seo In Guk from Reply 1997. The last feature is titled "Special Interview," and is 32 minutes long. It is a more formal interview with Infinite wearing their Chaser outfits and answering questions such as their childhood aspirations, when they knew they wanted to become singers, during their trainee days, what they plan to do 10 years from now, etc. My favorite was seeing Hoya go through the dance points of their songs~
Overall, before I received my One Great Step Returns concert DVD, That Summer Concert was definitely my most favorite of Infinite's concert DVDs. I absolutely loved the new and different arrangements of many of their songs and how they made them acoustic. Also the relaxed, casual vibe was cool as I could almost feel like I'm on a more personal level with Infinite. Now that the That Summer Concert 2 DVD has been released, I can't wait to see that one as well!
