I would tell the DJ to slow it down. Also, learn the names and artists of your favorite songs so that you can request them. It sounds like the DJ did not understand the need to provide more moderately paced music. Maybe he was used to working at latin clubs. Only very experienced salsa/mambo dancers in the clubs can effectively dance to the fastest music. However it is personal choice, no matter how experienced the dancers, as to the speed of music they prefer. I do not enjoy the fast music, for one because I enjoy ballroom Mambo and all the hip motion and other technical aspects that become practically impossible to execute with very fast music. Other dancers like to fly though their CBLs and spins and dips, which is fun to watch, but for this writer is not as sweet as nicely executed figures and technique to moderately paced music. Oh, and by the way, Salsa/Mambo music is typically faster than Cha-cha music. It is the slower tempo of cha-cha music that allows the additional syncopated cha-cha steps to be inserted. Dancing Salsa/Mambo to most cha-cha music is too slow. Thanks!
