Adele

After selling 30 million copies of her album '21' (2011) and playing at Barcelona's Bikini club that same year in support of the record, Adele is back in town for her European tour to present '25' (2015), her third album, which so far has broken sales records since its release. The British singer this time has moved to a much bigger venue at the Palau Sant Jordi, where she'll fill it with tears while she tries not to go hoarse from all the drama in her songs that are fast becoming classics of pop music.
