[2] Wanting to support the reconstruction of the city, Italian singer Jovanotti decided to call his colleague and friend Giuliano Sangiorgi, leader of the band Negramaro.

[3] Sangiorgi later declared: "We were thinking of what we could do, because for the first time the scenes broadcast by televisions didn't look distant, but extremely close to us and painful.

Therefore, we thought we could record a song, calling Mauro [Pagani] as the producer, in order to avoid doing things too close to the disaster.

[9] According to the charts compiled by Nielsen for the Federation of the Italian Music Industry, "Domani 21/04.09" was the best-selling digital single of 2009 in Italy.

[13] On 17 May 2009, the song also entered at number two on the Italian Music Control Airplay Chart, compiled by Nielsen, behind Gianna Nannini's "Attimo".
