The (hopefully) final mixes of my band's latest recording session.
Nothing makes me hate songs more than post-recording but pre-release listening. It's exhausting but necessary, especially when you're a control freak like I am. This is why I always want to get an outside person I trust to produce these things but no one else wants to pony up the dough to pay such a person.
Nothing like absolutely hating a song you wrote that you were once proud of.
