Brian Bromberg (born December 5, 1960) is an American jazz bassist and record producer who performs on both electric and acoustic instruments.
 Though he tends to gravitate towards the genre of smooth jazz, Bromberg has released some straight-ahead jazz records in which he performs with a trio, and has even ventured into more rock-oriented jazz fusion territory as of late.
 His innovative and technically demanding style of playing extends to both electric and upright bass.
 On his acoustic bass albums, Bromberg performs jazzy interpretations of various pop and rock staples from the 1960s and '70s completely solo.
 Regarding his work with electric bass, Bromberg, among other bassists, helped popularize the piccolo bass, or bass with each string tuned an octave up, by releasing several albums in which he plays both the bass line and melody.
 For instance, upon first listen many will be surprised to learn that, although soaring guitar can be heard throughout the album, Bromberg's 2005 release "Metal" contains only Bromberg on two overdubbed basses, one of which is heavily effects-laden to make it sound like an electric guitar.
The Art of Conversation is a studio album by English jazz bassist Dave Holland and American jazz pianist Kenny Barron.
 The record was released via the Impulse!
 Records label on October 14, 2014.
 The album contains 10 compositions: a mix of jazz standards and original tunes.
 The Jazz Journalists Association (JJA) recognized the record as the Record of the Year 2014.
