Well...I guess the difference usually lies in terms of artistic freedom not so much in terms of share of the profit created from album sales (granted that matters a lot too).
If u work in a group, even if u r a vocalist or the leader u still have to take into the consideration of other members of groups' wishes and thoughts when u r trying to create an album. I am not saying that's what always happens but it is how it is supposed to and usually happens theoretically. But if u r a solo artist...well the logic is u can sing and do whatever u want or wish to. So sometimes u see people doing totally different stuffs in their solo albums compare to the albums they have released while they were in groups. I kinda think Gwen Stefanie is a good example for this.
:blush: Then again...to be honest I dun see that much of the different in terms of creativity and music for Da's solo albums compare to her Endorphine albums. They still kinda sound alike... If u really wanna point something out, Da's solo effort sounds less of rock music and more closer to R&B... But I still love it. And I am still waiting to get my hands on da album hehe... :loool:
