Shell is probably the most amazing and original band you've heard little about, if anything at all, but will complete your sonic life upon first listen. Marianne Nowottny's solo stuff is amazing, but her band work, with her best friend Donna Bailey, is comparably mind-blowing. Comparisons to other genres or artists are impossible. Searingly original, Shell's lyrics cut through sentimental and juvenile mainstream fixtures. Shell creates poetic, swirling masterpieces of words and piano, guitar, and percussion, alternately grooving you and scaring you out of your skin.
