The name Spectra is used by two artists.

1) Spectra is an experimental band from Stockholm, Sweden. They play what they themselves call «groovy funkalicious semi‑progressive experimental metal» and are often recognized for their eclectic live performances. Their music can be described as some kind of party metal fused with funk, reggae and various ethnical influences.

Formed in 2009 from the remains of a metal project called Catch 22, Spectra has since it's formation focused on being a crazy live act. They started their career in a local band competition where they, despite their unorthodox music, managed to obtain the fifth place in total out of about 200 bands.

2) Spectra is an electronic music group from Italy. Their sound is specific, original and at times experimental and can be described as melodic morning trance.

With climatic melodies, dynamic bass lines and an overriding positive atmosphere Spectra display the talents they posses.They can be described in two words — 'Beyond Belief'.
