Avicii, stylized as ɅVICII, is a Swedish DJ, remixer, and record producer. The above is the instantly recognizable logo of Avicii, as can be seen on his early releases like the 2011 compilation album The Singles and the 2011 mix album Avicii Presents Strictly Miami.
This is probably a variant or redesign of the first Avicii logo, as you can see, the edges of letters in this logo tend to be sharper. This logo appeared on more recent releases like Wake Me Up and True, the debut album released in 2013. This logo is also used on the Avicii official website currently.
