"Alfonso is known as “El Mero Leon de la Sierra” or “the distinguished silver-headed living legend” among Tejano music fans...In 1998, Alfonso was inducted into the Tejano Music Awards Hall of Fame. In 2002, (he) was inducted into the Tejano R.O.O.T.S. Hall of Fame."
El Sonsonete was the B-side to El Silencio de la Noche. Both songs were on the 1973 Capri Records album, La Unica Mujer. This 45 is catalog #CA-265. The address on the 45 label is in McKinney, Texas. Cool.
The 45 label identifies the A-side as a Ranchera song, written by Mexican music legend José Alfredo Jiménez. El Sonsonete has the initials "D.A.R." where the songwriter credit usually is. Not sure what that means, maybe it's a traditional? The 45 label identifies El Sonsonete as cumbia.

Besides the McKinney address on the label, I couldn't find any info about Capri except that they also put out some Latin psych-funk back in '72 from Tony Hernandez & The Latin Liners. The Hernandez LP is called La Voz Encantadora. Back in '12, the guys at latinfunk.org posted the track featured in the Youtube video below, as well as the song Jo Tex, plus some biographical info about Hernandez. Gotta find me some Tony Hernandez.
