About 10 years ago, i had no job at all and have to earn some money for living. I knew a lot of popular songs and had no problem to learn any needed. Lead mussicians knew me as a bassist, but here in Latvia You try to earn as much money as possible and gig in as few people band (drummer, bassist not needed). It was pretty hard and i had to react on every call from band leaders who needed a biger band for party. Also the whole musical style was not my type so as soon i found a normal job i abandoned that mussicial type of life. Now i have a project of good potencials building up, full freedom for me and no stress at all, perfect for job/band life. The last way You can earn a good money as mussian, when You concentrate on one band who gets lucky to become popular and can make a big concerts and take good deals of business world, too.
