The issue is many industries don't have any exemptions. You can write 35 articles for a company before you need to be hired.

There is no exemption for musicians. Say your drummer is sick and your band is performing. You'll need to hire that drummer as an employee for the 2hour gig. Or said drummer will need to pay Cali $800/yr to form an LLC and perform contract work.

Music venue? Same thing. Either hire the performers as employees or the band needs to form an LLC and pay cali $800/yr.
