SYLENCER, the Chicago supergroup formerly known as ASYLUM, featuring band members Markus Johansson (lead guitars/lead vocals) and Johnny Rox (bass guitar), have released a trailer for their upcoming debut album, A Lethal Dose Of Truth, which will be released September 4th.

The trailer features segments from all sixteen songs appearing on the debut. Check it out below:

Sylencer will be releasing their debut album in Germany, Austria, and Switzerland via dPulse Recordings/Ovrtone Music Group, Inc. and distribution partners NEO MCC GmbH/Sony Music Entertainment Germany, and will be self-releasing their debut to the rest of the world independently via their newly formed record label, Sylencer Records, Inc.

Johansson commented: "The past six years have been a relentless pursuit to reach this point, and we are extremely proud to have completed this album entirely on our own. It has been a long and sometimes wild journey, with more ups and downs than we would've liked, but here we are, still standing. Working with all of the guest musicians on this record has been more than an amazing experience, and we are honored to have had them lend their talents to our debut album. To have accomplished this without a label, without financial backing; as two musicians with one collective goal, is beyond surreal and a dream come true."
