The Guachinangos are a band that blends bolero, cumbia, and son jarocho music making their own fusion genre. The band is led by singer, requinto, and jarana player Juan Carlos Marin. Although there is no website that states this, during the performance he was the front man and he was the one who signaled both musically and physically the different sections of the tunes they played. He was positioned center stage and was the main voice interacting with the crowd. To the right of Juan Carlos Marin, was vocalist and violinist Gabriella Grimaldi. In addition to violin and vocals, in other shows she also plays keyboards as well. In the far left is guitarist Alberto Fontes who often played the melodies on the electric guitar. When he's not he's playing rhythm parts helping keep the groove and add harmony to the music. Their bassist, Fernando Brindis is beside him and played an "electric accoustic" bass during the show. He also does vocals but had no mic at the performance attended. On the conga, center stage behind Juan Carlos Marin is Greg Lewis, who provides their main pulse in their music playing the conga. He is joined by fellow percussionist Victor Pineda Vasquez who played various percussion instruments throughout the night adding to the groove laid down by the conga player as well as adding colors. That seems to be the core group of the Guachinangos. They seem to vary in size based on the venue they're playing but the main players were described previously. In addition to the core members of the band, the band was joined by a special guest and a supporting percussionist that night. To the right of the guitarist, the special guest that evening was singer, dancer, and percussionist Julia del Palacio. All the way on the right was an auxiliary percussionist who played a guiro type of instrument and a marímbula. Although his name isn't found on any list put out by the band, it's logical to say that he is one of their accessory players brought in to "fill up" the music. The part he played on the marímbula helped fill the bottom up and the parts he played on the guiro doubling the maraca part as a counter point to the main groove.
