Pentatonix (often abbreviated as PTX) is an American a cappella group of five vocalists originating from Arlington, Texas. The members are Scott Hoying (baritone lead/harmony), Kirstin Maldonado (mezzo-soprano lead/harmony), Mitch Grassi (counter-tenor lead/harmony), Kevin Olusola (tenor/ percussion), and Matt Sallee (bass). Avi Kaplan was formerly a member of the group; he was replaced by Sallee in 2017. Their work, mostly in, but not limited to, the pop music style, consists of covers of pre-existing songs and some original material, sometimes in the form of medleys. Their music is defined by their own arrangement style, a strong presence of low bass vocals, and a diverse range of vocal percussion. The group's website is: www.ptxofficial.com.

Warsaw is a city with a tragic fate that survived considerable destruction, especially during World War II, when it was almost destroyed. But every time it is a city like a phoenix, reborn from the ashes. Today it is worth coming to Warsaw to see the magnificent restored palace complexes (the city center is listed as a UNESCO World Heritage Site), walk through the numerous temples, look into the modern Chopin Museum and interactive science centers. Tourists are also waiting for picturesque parks, jazz clubs and numerous sports facilities.
