There is more than one artist with this name:

1. The original band named Potion is the art rock electro-guitar-pop duo of Annie Maley (vox, electronics) and Michel Bedoya (vox, guitar). Potion makes romping, bruising, sophisticated, fuck-you pop music. Their music is a true synthesis of elements, blending modern sampling and synthesizer work, surf guitars, layered vocal harmonies, and ultra cool maracas! Bandcamp

2. Stoner/doom metal from Sydney, Australia
