Roberta singer

En Memoria

Roberta Singer PhD, Ethnomusicologist & Folklorist, was a member of LP21's Board of Directors since its beginning in 1992 until her passing in 2022. She researched, wrote about, presented, and produced Puerto Rican and Cuban music traditions for 40 years, including Somos Boricuas, LP21's first tour to Puerto Rico, Dos Alas tour, and Bomba-Dancing the Drum, a documentary film about the Cepeda family. Roberta also presented Puerto Rican and Cuban music traditions for 40 years with City Lore, with a mission to document, present, and advocate for grassroots cultures and ensure their living and traditions. Roberta was a close friend from the beginning, and her place in la familia de LP21 will always remain.

Que descanse en paz, Bobi.

~ A personal note from LP21’s Founder, Juan José ‘Juango’ Gutiérrez Rodríguez ~

Now, that the reader has the opportunity to know a bit about the fruitful voyage of Dr. Roberta Singer, perhaps it is the right time for me (Juango Gutiérrez) to mention a few of the many ways, most often personal, in which Bobi impacted and changed the course of what became Los Pleneros de la 21, and particularly, how our friendship of 40 years and counting, changed my life.

Bobi was a mentor, counselor, teacher, colleague, confidante, and above all, a dear friend, to whom I will be indebted for as long as I live. Early in our relationship, she sensed the passion that I had and continue to possess for Los Pleneros de la 21 and the many things that 'junte' meant in my life. Now I can clearly see that she worked tirelessly to make things happen for us, for our public, for our community, and of course, for me. It would not be accurate to say that for half of the things La 21 accomplished, she was a player. On the contrary, because she was a player, a mover, one accomplishment brought another, and so on. And here we are, still going forward while she is now all over the place and around embracing us. We feel you Bobi.

Roberta, mi amiga, te extraño. Por mi familia y por mí, gracias por la amistad y el amor.

Hasta siempre compañera, CAMARADA!!!!
