[6] Throughout the set list, only six musicians and four dancers[8] were employed to accompany her, with Aubrey Suwito in charged of composing and arranging the music for the concert.

[4] Siti was accompanied by Awi Rafael, Datuk Adnan Abu Hassan and Faizal Tahir for parts of the concert where the songs that were composed and written by them.

[12] She revealed that "Jawapan di Persimpangan", the first track from her debut album was the first song she recorded when she was under the tutelage of Datuk Adnan Abu Hassan.

[9] Siti reminisced the moment when she was taken from Subang airport after arriving from Shanghai straight to Langkawi by a helicopter to perform for an event that was attended by Tun Dr. Mahathir Mohamad.

[9] She was excited she was to meet Tun Dr. Mahathir Mohamad (who was still a prime minister at the time) and break the news personally to him that she just won the Gold Award from the Asia New Singer Competition in Shanghai in 1999.

[13] Later she also invited Datuk Adnan Abu Hassan to accompany her on piano to the songs that were written and composed by him, "Jerat Percintaan" and "Gelora Asmara".

She told the audience, "Abang D (Adnan) is among the individuals that is responsible of taking me into this industry, I actually once stayed at his house back when I was becoming an artist.

[12] The final medley was three songs from Fragmen written by Indonesian songwriters and composers — "Sanubari", "Terbaik Bagimu" and "Kau Sangat Bererti".

[12] She finished the show by performing all the songs from Fragmen that were released as singles including "Jaga Dia Untukku", "Lebih Indah" and "Seluruh Cinta".

"Konsert Unplugged Datuk Siti Nurhaliza" last Tuesday night at Istana Budaya is not just a typical concert to be watched.

"[e][11] Siti's vocals referred as "merdu" (sweet) by Syanty Octavia Amry of Harian Metro,[5] Dhiya Aizat of Tonton Extra,[1] Nurfarhana Mohamed of Utusan Online[4] and Shazryn Mohd.

[12] Nina Farzuin Md Sharom of Sinar Harian praised Siti's vocal performance even after more than twenty years being in the industry.

[12] Che'AZ, reviewer from the English version of The Rakyat Post commented, "Siti not only drowned her audience with her powerful vocals, she also proved to them that she is truly in a league of her own by mesmerising the entire crowd with her melodious arrangements.

"[15] A number of reviewers also agree that one of the most poignant moments of the concert was when Siti invited her former mentor, Datuk Adnan Abu Hassan to the stage to accompany her on piano while she is belting songs of his creation - "Jerat Percintaan" and "Gelora Asmara".

[16] The reviewer further commented, "Even though Datuk Adnan's health condition is still unstable and it was said he's having a stroke, his spirit to be with Siti Nurhaliza is strong although he had to be helped to get on the stage.

That slot managed to make the audience in the hall to feel wistful and melancholic, but with Adnan's fingers playing the piano is proving that he is still able to perform and further beautify "Konsert Unplugged Siti Nurhaliza".

[14] Rosli Manah of Mangga Online whom Siti personally thanked for being the first journalist[9][14] to interview her during her early years also noted the same fact.
