Benjamin Sobel, Director

Ben hails from Seattle, WA where he earned a Bachelor’s degree in music, with an emphasis on voice and composition, from the Cornish College of the Arts in Seattle. His experience and involvement with vocal music has been highly varied and includes time as a music director and sound designer, as a music educator and administrator and, of course, as a barbershopper in the Olympic Peninsula Men’s Chorus.


A chance to escape the grey winters of Seattle brought him to Oahu in 2016 where he quickly immersed himself in the local musical community. Ben sings and composes for the Lutheran Church of Honolulu, toured Italy as a featured singer with the Honolulu Chorale and performed as “Francis Flute” in Diamond Head Theatre’s recent production of “Something Rotten.”


Since his arrival in the islands, Ben has done seasonal singing with a barbershop quartet and began working with Honolulu Blend in 2019. He takes pride in the chorus' “clear and focused quality” and enjoys that the group “is fun and works well together.” Honolulu Blend is happy to have Ben on its musical journey!

Rachel Knapstein, Baritone

     It was a balmy November evening when Rachel, and her now husband, were strolling through Ala Moana Center and happened upon Honolulu Blend Show Chorus performing at center stage. Rachel first joined HBSC as a guest for a holiday workshop and performance and hasn't turned back.

     Rachel grew up in Forest Hill, Maryland as a self-proclaimed choir nerd. She competed in the National Eisteddfod of Wales, the largest festival of competitive music and poetry in Europe, with her high school a capella choir. As an adult, she sang with her local church choirs, but since moving to Hawaii in 2010, she had been itching for a different chorus experience and HBSC gave her the fun and friendship that she was looking for.

     Rachel has always been a "harmonizer" so the baritone part suits her best. She joined the chorus in 2014 and sang baritone in the quartet Candid Connection at Regional contest in 2016. Aside from singing, she enjoys surfing and sailing. Rachel has a master's degree in marine science and currently works as a biologist at an environmental consulting firm in Kaneohe.
