Leendert Wouter "Leon" Bolier (Dutch pronunciation: [ˈleːjɔm boːˈliːr]; born 21 October 1980), also known by his mononym Bolier, is a Dutch trance DJ and record producer.
He has had his songs played by top DJs like Tiësto and Armin van Buuren[3] as well as his tracks appearing on famous trance compilations such as In Search of Sunrise 4: Latin America and A State of Trance 2006.
By the following year, which coincided with his complete dropping out of DJ Mag's list of the top 100 DJs, his musical style began to change, as depicted in "Disco Davai" among others.
At the end of 2014, Bolier started working on his third album under his new alias WSTLNDR.
The 12-track work, titled Atmostopia, featured his complete return to his original creative roots which were not seen in his repertoire since the release of Phantasma.
