Artists plugin

Hello everyone,

I’m building an artists website for a non-profit project studio.
The idea behind my website is to help artists create, record and showcase their work for free.

I’ve managed to build myself a system so that I can manually add artists, artists pages. But I don’t think it’s very convenient system to work with.

I’m looking for something to replace my system that can:

-Add artists
-Add albums
-Add Biography page or tab
-Add Discgraphy page or tab
-Add Music, video, photo Gallery

I’ve tried everything I could find, including

WPArtists
ribcage by Records On Ribs
Band manager
Etc…

Could someone please help me find a replacement system?
Thank you.
