Question: Dive bomb was a guitar technique used by the co-founder of Pantera, who also founded what band?
Context: String bending is a guitar technique where fretted strings are displaced by application of a force by the fretting fingers in a direction perpendicular to their vibrating length.  This has the net effect of increasing the pitch of a note.  String-bending allows exploration of microtonality and can be used to give a distinctive vocal articulation to lead guitar passages. Transfer is a technique used in propaganda and advertising.  Also known as association, this is a technique of projecting positive or negative qualities (praise or blame) of a person, entity, object, or value (an individual, group, organization, nation, patriotism, etc.) to another in order to make the second more acceptable or to discredit it.  It evokes an emotional response, which stimulates the target to identify with recognized authorities.  Often highly visual, this technique often utilizes symbols superimposed over other visual images.  An example of common use of this technique in the United States is for the President to be filmed or photographed in front of the country's flag.  Another technique used is celebrity endorsement. A guitar battle (or "guitar duel") is where two or more guitar players take turns soloing, either with or without a rhythm section.  The purpose of the guitar battle is to determine who among each of the guitar players present is the most proficient on the instrument.  Often, it begins with the guitarists trading licks and phrases, while gradually increasing the complexity of the technique used.  A guitar battle can be said to be over when one guitarist outplays (either through skill, endurance or the other guitarist(s) acknowledging that they cannot win) all the other guitar players present.  This is also known among guitarists as a "head-cutting" duel or simply as "cutting heads". A pick slide or pick scrape is a guitar technique most often performed in the rock, punk or metal music genres.  The technique is executed by holding the edge of the pick against any of the three or four wound strings and moving it along the string.  As the pick moves across the string, the edge of the pick catches the string's windings in rapid succession causing the string to vibrate and produce a note.  This rapid rattling of the pick's edge against the windings also gives the resulting note a grinding or grating quality. 25 Studies, Op. 60 is a set of etudes for the classical guitar, written by Matteo Carcassi.  The etudes serve as a bridge between the elementary and advanced intermediate stages of the discipline, and are based on simple harmonic structures.  They contain many of the fundamental elements upon which guitar technique rests, for example, arpeggios, slurs, barres, etc.  Each study attends to the treatment of a particular technical challenge.  The etudes also accustom a pupil to various tempos and the various positions on the guitar. Marcus Henderson (born March 16, 1973) is a rock and heavy metal guitarist from the San Francisco Bay area.  His previous bands include Drist and Hellbillys as well as work for En Vogue and Simon Stinger.  In 2005, he was chosen to take the role as one of the lead guitarists for the "Guitar Hero" series.  Marcus is also the on-screen guitarist for the Hal Leonard DVD books "Metal Guitar" and "Guitar Technique". Falsettone is a term used in modern Italian musicology to describe a vocal technique used by male opera singers in the past, in which the fluty sounds typical of falsetto singing are amplified by using the same singing technique used in the modal voice register.  The result is a bright, powerful tone, often very high-pitched, although the sound is still different from and more feminine than what is produced by the modal voice.  The term "falsettone" is also used for the mixed vocal register that can be achieved using this technique. Darrell Abbott (August 20, 1966 – December 8, 2004), also known as Diamond Darrell and Dimebag Darrell, was an American musician and songwriter who was a co-founder of Pantera alongside his brother Vinnie Paul, and founder of Damageplan.  He was considered to be one of the driving forces behind groove metal. Dive bomb is a guitar technique in which the vibrato bar is used to rapidly lower the pitch of a note, creating a sound considered to be similar to a bomb dropping.  One of the most recognized pioneers of this technique is Jimi Hendrix.  Other notable musicians who are widely known for using this technique are Herman Li, Eddie Van Halen, Brian May, Joe Satriani and Tom Scholz of Boston.  Some guitarists, such as K.K. Downing, Glenn Tipton, Jeff Hanneman and Dimebag Darrell have been known to use a variation of this technique in which a harmonic, most commonly a pinch harmonic, is used instead of a normal fretted or open note creating a sound arguably closer to that of a bomb due to the squealing sound created by the harmonic. Tambour (also called tambor, tamboro or tambora, written in music as tamb.) , is a technique used in Flamenco guitar and classical guitar which is designed to emulate the sound of a heartbeat.  It is achieved by using a flat part of the hand, usually the side of the outstretched right thumb, or also the edge of the palm below the little finger, and sounding the strings by striking them rapidly just inside the bridge of the guitar.  Durations from a single articulation to an extended drum roll tremolo are possible with this technique.  If performed incorrectly, the effect is similar to a right-hand apagado, or dampening of the strings.
