Alt-J An awesome wave - it really is considered as a whole in its creation. There are interludes, dips & swells in the energy, and a whole journey of sonically related songs which keep introducing new variations and sounds.
Sufjan Stevens the BQE - another album that really should be enjoyed as a whole journey, it follows the daily commute of so many along the Brooklyn Queens Expressway in NYC. It wanders from orchestral to electronic noise, and is a wonderful album to put on for a slow Sunday morning.
I started an all-trans punk band online, and my usual music is singer-songriter. The new project really pushed me, and turns music making into a social activity! I also started another solo project that is 100% cello covers of contemporary songs (last one I did was “girls just wanna have fun”). Both of these projects push me out of my usual, and breathe some fresh air into my music. Maybe you could find some ideas that pushes you out of your comfort zone?
