The band recorded ten studio albums, three of which have been certified Gold in Poland, and established such evergreen hits as "Chodź, pomaluj mój świat", "Windą do nieba" and "Iść w stronę słońca".
They have won a number of local and international awards, and performed in countries around the world, such as Germany, the Soviet Union, the United States, Canada and Cuba.
The band performed "Już nie będę taki głupi" at the festival in Kołobrzeg and recorded their first EP, which featured four folk-flavoured songs.
In addition to two previously known hits, it included the songs "Wstawaj, szkoda dnia" and "Hej, dogonię lato" which also became popular.
[3] The group then performed the song "Zjechaliśmy kapelą" on the German TV show Disco and were met with a warm reception.
That same year, the band recorded the hit song "Gwiazda dnia" for the movie In Desert and Wilderness, based on Henryk Sienkiewicz's novel of the same name.
The group made an appearance on the all-star TV special Piosenki z autografem, performing "Na luzie", alongside such artists as Anna Jantar and Danuta Rinn.
Their second LP, Wyspa dzieci, was a concept album and turned out to be another success, including the previously known hits "Gwiazda dnia", "Kołysanka matki" and "Na luzie" as well as the popular title song.
The musical spectacle, showcasing a more sophisticated sound than the group's previous efforts, premiered in Opole in 1976 and received significant praise.
Andrzej Krzysztofik left the group and was replaced by Cezary Szlązak, forming what would turn out to be the band's most successful line-up.
In the early 1977, on the 10th anniversary of Cybulski's death, the band started to work on their third studio album, Aktor, based around the previously known musical spectacle.
Other notable songs on the LP included "Ding-Dong", "Romanse za grosz" and "Ballada łomżyńska", the latter with a contribution from the legendary Polish musician Czesław Niemen.
Their double A-side single, featuring the songs "Margarita" and "La Habana mi amor", was the first record by a Polish artist ever released in Cuba.
In 1982, 2 Plus 1 released a new wave-inspired double A-side single, with the songs "Kalkuta nocą" and "Obłędu chcę", which enjoyed considerable popularity.
In 1983, the band gave a critically acclaimed avant-garde performance at the Opole Festival, where they premiered songs from their forthcoming album.
Their eighth studio LP, Bez limitu, introduced the band's new image and musical style, which now explored new wave, rock and synthpop.
The LP spawned further hits "Video" and the Polish-English "Chińskie latawce", the latter a duet between Elżbieta Dmoch and John Porter.
In 1985, Cezary Szlązak released a solo single, featuring songs "Bezpłatny kurs" and "Inne życie, inny świat".
In 1987, Janusz Kruk started to compose music for theatrical plays, including Szaleństwa pana Hilarego, based on Julian Tuwim's short story.
In 2002, Elżbieta made a guest appearance at a community centre in Łomża, where a teenage group staged a play as a tribute to 2 Plus 1 and their music.
[7] In the mid-1970s, two additional musicians supported the band: Adam Pilawa (piano, violin) and Andrzej Wójcik (drum kit).
