Context paragraphs:
Sheila Landis: Sheila Landis (born Sheila Catherine Landis 9-10-1953 in Detroit) is an American jazz and R & B vocalist and songwriter.  Landis formed her own label, SheLan Records, in 1981, initially releasing five albums of self-penned material.  These original vinyl recordings are avidly sought out world-wide by jazz record collectors.  Much of this material has been released internationally on Counterpoint Records UK and Celeste/Vivid Sound in Japan.  In 1990, Landis began working with guitarist/producer Rick Matle in live performance and in the studio.  Together they have released over 10 recordings.  Sheila is a 7-Time Detroit Music Awards "Outstanding Jazz Vocalist" Winner, along with being recognized for "Outstanding Traditional Jazz Group" and "Outstanding Jazz Composer" (co-winner with Rick Matle).  Landis draws inspiration from vocal artists Sarah Vaughan, Flora Purim and Joni Mitchell.  Motown, Brazilian bossa nova and samba, classic rock and pop have also been influences in forming her soulful sound amalgam.  David Nathan of AllMusic writes, "Landis has an extraordinarily flexible voice and an uncanny ability to use it to great advantage.  She scats, sings ballads, loves Latin rhythms, and can swing.  She does jazz, rock, bebop, as well as Latin with absolute equanimity.  Although having been on stage for more than 30 years, Landis has never fallen into a rut.  Her work continues to exude vitality, excitement, diversity, and originality".  Not content to simply sing and scat in the jazz vocal tradition, Landis takes the lead from vocal innovators Al Jarreau and Bobby McFerrin in expanding her vocal palette to include uncanny imitations of the harmonica, trumpet, flute, synthesizer, string bass and even drums.

Pawn Ticket Trio: Pawn Ticket Trio is a jazz band based in Denver, Colorado.  The group is self-categorized as playing "hack jazz", a style fused with rock structures and jazz stylings set to humorous lyrics and attention to solos.  The group formed in late 2007 as an effort to bring the songs of guitarist John Lambert to a wider audience, and to serve as an experiment for a group of people who had always liked jazz in their own ways, but had never had a chance to play it.  The band consists of founding members John Lambert on guitar, Bret Ahroon on bass, and Stephen Brooks on drums.  Early in 2008 the band experimented with a young trumpet player by the name of Dan Madden.  Shortly after a couple of live shows they added Mr. Madden to the band on a permanent basis.  In 2009, Lambert and Ahroon asked Keith Larson to join the band on trombone, and Matt King was added to play the saxophone.  They do however continue with the "trio" name as the band was initially incepted as a three piece.
