In the artist's words:

After the last Hogwarts school reform from G7 to G6, a group of rebellious students broke away from the four known houses and founded the fifth magical house "Ragoody" in a bouncy castle on the lake outside Hogwarts. After realizing that they could neither do magic nor play Quidditch, they decided to form a band.
Since that day, the Ragoody Orchestra has been delighting its fans with punk 'n' polka and a ragoody stage show. Ragoody means: beer-stained floor, party, magic show, singing along, singing along and jumping along to covers and our own songs. Our own songs describe, for example, the best evening of your life, the tastiest beer in the world or the world's best machine rental. If you have the choice between ________________ [enter any other band name here] and the Ragoody Orchestra, we strongly recommend the Ragoody Orchestra for the benefit of the audience!
