Razlog (Bulgarian: Разлог) is a town and ski resort in Razlog Municipality, Blagoevgrad Province in southwestern Bulgaria. It is situated in the Razlog Valley and was first mentioned during the reign of Byzantine emperor Basil II.

During his 1894–1896 trip in the region of Macedonia, Bulgarian geographer Vasil Kanchov visited Razlog (then known as Мехомия, Mehomia) and reported that it numbered 820 households, of which 500 of Eastern Orthodox Bulgarians, 300 of Muslim Bulgarians (Pomaks), 16 of Protestant Bulgarians and 5 of Eastern Orthodox Aromanians, for a total population of around 4,620.[1] According to the same author's 1900 study on the population of Macedonia, Razlog was populated by 4,970 people, of which 3,200 Christian Bulgarians, 1,460 Muslim Bulgarians, 80 Turks, 200 Roma and 30 Aromanians.[2]

The town's population actively participated in the Kresna-Razlog and Ilinden-Preobrazhenie Uprising, Razlog, which was part of Serez sanjak in Selanik vilayet as "Razlık", itself being liberated from Ottoman rule in 1912. Razlog has developed as a centre of winter tourism in the 1990s and 2000s owing to its favourable position in the vicinity of the Pirin, Rila and Rhodope mountains.

Parni valjak ("Steamroller") 1975 is a Croatian and former Yugoslav rock band. They were one of the top acts of the former Yugoslav Rock scene, and currently one of the top rock-and-roll bands in Croatia.

Parni valjak was founded in 1975. Unlike many rock bands that would come later, their style was becoming more mainstream, becoming closer to pop, especially compared with the bands like Prljavo kazalište or Film.

As years went by, their refusal to change style proved to be the important factor in the band's longevity. They kept a loyal following in 1980s and in 1990s, refusing to allow elements of folk and turbo folk music to become part of their repertoire. Because of that the band enjoys great respect among many Croatian rock critics, being seen as the embodiment of "true" rock and urban culture and many of their songs are considered evergreens in the former Yugoslavia like "Sve još miriše na nju", "Jesen u meni", "Ugasi me" and "Zastave". Parni valjak kept a relatively small but dedicated following for 30 years, and many people tend to gather at their concerts that feature energetic performances, despite advanced age of the band's members: Aki Rahimovski - vocals, Husein Hasanefendić-Hus - guitars, Marijan Brkić Brk - guitars, Berislav Blažević-Bero - keyboards, Zvonimir Bučević-Buč - bass guitar, Dražen Scholz-Šolc - drums, Tina Rupčić - vocal, Anita Mlinarić - sax.
