Long before "supergroup" became a music industry buzzword, Elektra Records assembled one of the format's earliest and most electrifying experiments: Rhinoceros, a late-1960s heavy-soul/rock outfit whose blend of muscle and melody made them favourites among musicians and critics who understood exactly what they were witnessing. Decades later, Rhinoceros remains one of rock's great under-the-radar treasures, a band cherished by those who found them and overdue for discovery by those who have not.

Founding member Alan Gerber, the pianist, multi-instrumentalist, and songwriter whose fingerprints have been on soul and blues music for half a century, is giving a new generation every reason to go looking, with the arrival of his new single "Over Again," the latest offering from his new album 'The Well.'
