Chicago

Similar to Blood, Sweat & Tears in construction and style, Chicago became a multi-million dollar industry with five consecutive number one albums, although their hit single If You Leave Me Now remains their most memorable moment.

The band originally played across the USA as Chicago Transit Authority, until legal action from the city's transport company resulted in the shortened name.

With a core rock quartet of Terry Kath (guitar and vocals), Robert Lamm (keyboards and vocals), Peter Cetera (bass and vocals) and Danny Seraphine on drums, along with the trio of Lee Loughnane (trumpet), James Pankow (trombone) and Walter Parazaider (woodwind), the group were able to craft both energized pop and leftfield jazz-rock concurrently.

HISTORICAL NOTE
On January 23 1978, Terry Kath was showing off a pistol from his gun collection. When his friend asked him to be careful, Kath replied, "Don't worry, it's not loaded". 

He then put the gun to his head and pulled the trigger. It turned out that there was still one bullet in the pistol.
