In 1991 Tralla released their first Ska cd, the debut album of Dr. Calypso. Nearly 10 years after Tralla has launched a very important part of the Spanish Ska bands, maybe one of the most fruitful Ska scenes in the Europe. Komando Moralis, Dr.Calypso, Skaparrapid... the bands who started it all are still on stage. 15 bands, 19 tracks and over 1 hour of nonstop Ska!!!
