The second half of Roxette, Per Gessle, has gone through the band's huge music archive and found unreleased songs and raw demos of their biggest hit songs.

Demos that have never been released before.

The album Bag of tricks, which will be released tomorrow, is the first of four compilation volumes with the band.

-Bag of tricks is a collection of unreleased Roxette material, a whole lot of demos.

There are some acoustic songs that we recorded in the Abbey Road studio, just a take where Marie is fantastic, so she would have loved this, says Per Gessle.

The compilation album is released just over a year after Marie Fredriksson died last year.

- I was quite prepared for Marie to pass away. At the same time one thing to say that it is not possible to prepare. Without it it becomes an emptiness. I miss the relationship. To call, quarrel, laugh and so on, says Per Gessle.
