The Baroque orchestra is the type of orchestra that existed during the Baroque period, commonly identified as 1600-1750. Its origins were in France where Jean-Baptiste Lully added the newly re-designed hautboy and transverse flutes to his vingt-quatre violons du Roy. As well as violins and woodwinds, the baroque orchestra contained continuo instruments such as the theorbo and harpsichord.

In the Baroque period, the orchestra was not standardised in size. There were large differences in size, instrumentation and playing styles - and therefore orchestral soundscapes and palettes - between the various European regions. The 'Baroque orchestra' ranged from smaller orchestras (or ensembles) with one player per part, through to larger scale orchestras with many players per part. Examples of the smaller variety were Bach's orchestras, for example in Koethen where he had access to an ensemble of up to 18 players. Examples of large scale Baroque orchestras would include Corelli's orchestra in Rome which ranged between 35 and 80 players for day-to-day performances, being enlarged to 150 players for special occasions.

Sebastian Bach (born April 3, 1968) is a Canadian heavy metal singer who achieved mainstream success as frontman of Skid Row from 1987 to 1996. Since his departure from Skid Row, he has had many television roles, acted in Broadway plays, and led a successful solo career.

Bach was born Sebastian Philip Bierk on April 3, 1968, in Freeport, Bahamas, and raised in Peterborough, Ontario, Canada. He attended nearby Lakefield College School in the same class as Michael Kulas, of the British rock group James, a year behind Felipe, Prince of Asturias and a year ahead of the comedian/actor Will Arnett. He is of Norwegian, French Canadian, and Native American descent. Bach's father was the visual artist David Bierk. He is the brother of retired NHL goaltender Zac Bierk, model/actress Heather Dylan Bierk, and Toronto-based artists Jeff, Nick, Alex, and Charles Bierk.

Skid Row initially formed in the late eighties with lead singer Matt Fallon. They began playing at various New Jersey clubs. Fallon would soon leave the band in 1987, leaving Skid Row without a singer. Bach, who had just left his previous band Madam X, was spotted singing at rock photographer Mark Weiss's wedding and the members asked him to join. He turned them down, but changed his mind after hearing the demo tapes of "Youth Gone Wild" and "18 and Life". He sent them a demo of him singing "Saved By Love." They loved it and flew him to New Jersey where they began playing gigs. Sebastian also recorded demos with Bon Jovi & Sabo's friend Jack Ponti. (The song "She's on Top" later came out on Jack Ponti Presents Vol. 1)
