For instance, take the one that says âThose who can, do; Those who canât teach.â Well, in the case of Philadelphia native Keisha Hutchins Hirlinger, nothing could be further from the truth. A bonafide singer/songwriter who has already produced three CDs, and whose musical talents have been displayed everywhere from Carnegie Hall to local clubs, Hirlinger is also a much sought-after teacher. Classically-trained at the prestigious Oberlin Conservatory of Music, Hirlinger says she has been exploring, blending and bending all kinds of music, from hip-hop, to country, to the classics, to R&B, and everything in between. âI was always singing, so, for me, being a musician is who I am,â Hirlinger says. âI always wanted to sing and share my music with others. I donât think I ever had dreams of becoming rich and famous. I just wanted to be able to make a living with my music. And even though today I teach full time at Abington Friends School as well as privately, I also still perform as much as possible.â
