High Quality Content by WIKIPEDIA articles! Electro (short for either electro-funk, or electro-boogie) is a genre of electronic dance music directly influenced by the use of TR-808 drum machines, and funk sampling. Records in the genre typically feature drum machines and heavy electronic sounds, usually without vocals, although if vocals are present they are delivered in a deadpan manner, often through electronic distortion such as vocoding. This is the main distinction of electro from previously prominent genres such as disco, in which electronic sound was only part of the instrumentation rather than basis of the whole song.
