Straight out of high school, he began touring with several bands and soon after that produced his first solo album, Del '63, which was released in 1984. It was promoted first in his home town, but later earned attention in Buenos Aires. The recording was put together with the help of some of Argentina's most prominent musicians, including Daniel Wirtz, Fabián Gallardo, Tweety González and Paul Dourge. The disc won him critical acclaim as a songwriter and helped lead to future projects, including a 1985 album, Giros. The demo of that album earned him the praise of Luis Alberto Spinetta, as well as a partnership – Paez's next album, 1986's La La La was a duet with Spinetta. The duo supported that album with a tour that reached all the way to Santiago, Chile. The same year, he participated in the Thousand Days of Democracy festival.
