Scott Bradlee & Postmodern Jukebox - Swansea Arena

Starting out as the bedroom project of Jazz pianist Scott Bradlee and rapidly growing into a viral and real-world sensation, the US group's vintage-pop mash ups have racked up over 811 million views on YouTube.

Imagine marrying the 21st century party vibe of Miley Cyrus or the minimalist angst of Radiohead with the crackly warmth of a vintage 78 or the plunger-muted barrelhouse howl of a forgotten Kansas City jazzman. Bradlee's choice of material ranges from the '80s hard rock of Guns N' Roses to hits as recent as Taylor Swift's controversial "Look What You Made Me Do." They're rendered by a rotating cast of musicians and singers in fashions that date back to a time when Axl, Slash and T-Swift's parents had yet to be born - a time of street corner harmonies and torch singers, blues belters and golden-voiced crooners.
