This tanda comes from Dj Goran from Zagreb, Croatia. Here's what he had to say about the tanda:

I sometimes play other songs in combinations with these, such as "Vamos, vamos zaino viejo" or some with Carlos Barrios, but these are my favourites from Fresedo's 50s. Especially "Pero yo se" and "Paisaje". Since those songs are not often played, I usualy start with "Pero yo se". "Patotero sentimental" is a familiar piece to most dancers, but I think "Pero yo se" is very recognisable lately (e.g. Chicho performed to it many times). Paisaje is something really unexpected. Many dancers asked me if it is some Christmas song because of the bells.
I live and work in Zagreb, Croatia. Although I am a physicist, my 10 years of piano school are much more useful in tango. I don't have any regular event unfortunately, since this is a very small community but I did manage to visit quite a few places in the past 1.5 year of serious DJing.

Thank you Goran! A bit more information for those who like the opening track: The beautiful "Pero yo se" was composed and written by Azucena Maizani. She also recorded the song in 1928 and 1931 (listen on Spotify). Also D'Agostino recorded the song with Vargas (listen on Spotify).
"Patotero Sentimental" is probably best known as the versions from Di Sarli with Rufino (listen on Spotify) and also Di Sarli with Pomar (listen on Spotify).
