"Bull y los Búfalos" is a rock band formed in 2002 in Madrid by recognized musicians from different backgrounds with Bull (Diego Avello) as its frontman.

Bull was born in Cangas del Narcea, Asturias. He formed his first band there and toured across Northern Spain giving numerous concerts under the name of "Dalton Rockers". Later on, he participated at different festivals with the band "Profetas" where he was the lead singer and Jorge Martinez (from "Ilegales") played guitar. This line up ended after the recording of a LP that never got to see the light. After this, Bull integrated one of the songs to "Bull y los Búfalos"'s repertoire and Jorge Martínez published the complete list of songs with his band "Ilegales".

After leaving "Profetas", Bull decided to move to Madrid. Once in the capital, the 6'6 tall Asturian singer recorded the video for "Héroe de los Gatos" and formed "Bull y los Búfalos" again, along with guitarist Antonio Berdiales "Berdi", bassist Javier Cano (from "La Guardia"), drummer Rodrigo Lopez, and Roberto Collado's harmonica. This line up toured throughout various Spanish stages, while writing several songs together.

In 2007, band members changed completely and finished recording their first LP "¿Quién dijo Miedo?". The recording was performed by both, the newer and previous musicians. The album consisted of eight original songs (lyrics: Bull, music: Bull and Berdi) and two covers: Elvis Presley's "Paralized" and "Motín en la Prisión" (taken from "Profetas" with Jorge from "Ilegales" as collaborator).

The entirely self-produced album was released on October 15th, 2009 under the label "Circular Música", who published and distributed it in stores and online. The showcase took place in Madrid at "La Sal".

After recording the video of one the album's singles, "Alguien Mejor que Yo", an intense tour throughout many Spanish cities and small towns began, managed by band members with the help of booking manager Jaime Ortueta. There was no doubt that live shows were where the band shone the most. Guitarists Nico Álvarez (from "La Frontera") and Igor Paskual (from "Los Trogloditas") were featured in this tour.

After finishing the tour in winter of 2010, the band had sold an impressive amount of album copies and had received great media reviews, both in print and digital. The band decided to take advantage of this positive flow and began writing for a second LP.

"Bull y los Búfalos" recorded its second album in Madrid with a more Sourhern Rock style sound and production, introducing pedal steel, dobro, and harmonica to its instrumentation. The LP consisted of seven original songs (lyrics: Bull, music: Bull and R. Bustillo), two covers, and a song featuring Carlos Segarra (from "Los Rebeldes") and Igor Paskual (from "Loquillo y los Trogloditas").

This album was produced by Bull and Miguel Ángel, recorded in Madrid, mixed in Los Angeles by Alberto Sánchez, and mastered in New York by Vlado Meller, one of the top mastering engineers at the time.

This line up worked very well and brought up excellent results and opportunities (several TV and radio appearances: "Radio Reactor" and "40 Principales", and press reviews). Also, Bull was selected to write "Enmascarado", the theme song for "Mundo de Lucha Libre", featured in national TV and radio, and included as a bonus track in the album.

Going to Mexico represented a real success full of appearances at festivals. The band stood out as the most featured at Biker Rock festivals, such as "La Semana de la Moto en Mazatlan" (the largest in Latin America, where it performed twice in front of 20,000 people while sharing the stage with renowned Mexican rock artists), "Love Ride" (sponsored by Harley Davidson), "Moto Fiesta León", "Motorcycle Expo", and other rock and motorcycle events.

In addition to its several tours and concerts at Mexico City's most important nightclubs ("Bulldog" and "El Imperial"), "Bull y los Búfalos" was nominated by "Rock and Road" forum as best live rock band.

Besides numerous press presentations and concerts, two excellent videos directed by "Once Producciones" were shot for the singles: "Me Voy a Echar de Menos" and "Quiero". Both were transmitted in specialized music channels such as "TeleHit" and "Canal Once".

The band is currently preparing a tour throughout several cities in Southern USA.
