What do you get when you blend the lyricism of Ed Sheeran & the swagger of Drake? People around the world that have seen Almost Owen perform know the answer.

Isaac Haselkorn, better known as Almost Owen (AO for short) began performing as a drummer in dive bars and jazz clubs from the early age of 11. 

A few years later while studying at Berklee College of music, he grabbed the attention of grammy winning musicians Jamey Haddad and Danilo Perez, who would include him in studio sessions, tours and performances with Paul Simon, Wayne Shorter, Joe Lovano and other jazz legends. 

Their advice? Travel internationally, study broad music styles, and perform for audiences everywhere. 

Four years and 500+ shows across 12 countries later, AO is back in his home city of Boston, winning acclaim from fans and critics alike for his undeniable songwriting and electric performances.

Based on the groundswell of support from his growing local following,The Improper Bostonian named him one of the 25 most influential personalities in the city. His most recent single "I Should Know Better" is currently in rotation on I Heart Radio syndicated stations in Boston, New York, Nashville, Atlanta, and Connecticut.
