Two great musicians, Lluís Gómez on banjo and harmonica player Joan Pau Cumellas, present the Barcelona Bluegrass Band project. This group is primarily dedicated to playing the original music of the Appalachian Mountains of the USA. However, they enrich the traditional sound with touches of blues, country, jazz and Celtic music. The other band members are Miguel Talavera on guitar and dobro and Maribel Rivero on double-bass. All of the band are specialists in bluegrass which is a demanding style and one which captivates lovers of acoustic music. While paying homage to the music of the mountains of North America, the group also plays its own compositions, giving a modern and personal touch to this musical genre. This formation presents a modern concept of the banjo, and is one of the few in the world that includes the harmonica as a lead instrument in this context. This has led them to being very well received in numerous festivals both in our country and in Ireland, England, Holland and France. After the good international reception of the CD ?Barcelona Bluegrass Band? (2009) with Oriol Saña, Robbie K.Jones, Ricky Araiza, Albert Bello and special guests from Nashville such as Tim Carter or Alison Brown, we now present our new work entitled 'Old Time Blues' (2011). This is an album where bluegrass meets the classic sounds of blues and jazz, with Oriol Saña, Robbie K. Jones, Valentín Moya, Albert Bello and Josep Traver. A special guest from the USA, the great banjo master Tony Trischka, collaborates on two tracks. Following the line of his first CD, Lluís Gómez creates compositions with his banjo which fit perfectly with the sound of Joan Pau's harmonica. This gives a unique touch to this acoustic formation.
