Featuring the Southern California Children’s Chorus, Aerosmith reworked their classic ‘Dream On’ as a moving tribute to the victims of the Boston Marathon Bombing.

Steven Tyler and Joe Perry, aka the Toxic Twins, join the choir for a concert in a vast cathedral that is both beautiful and eerie.

The arrangement is radically different from the original, with Tyler’s piano and Perry’s guitar being the only instrumentation, producing a stark and ominous vibe.

In addition, Perry’s gloomy guitar riffs complement Tyler’s somber vocals, which he completely reworks to transform into a moving dirge.

There are perhaps a couple of dozen teenage singers in the choir, and their pitch-perfect harmonies

really set the mood for the piece. Below is the 52 million-view performance that has gone viral on YouTube.

Throughout the song, Tyler truly puts everything into it, giving a fantastic vocal performance. In the meantime,

Perry turned up the effects on his guitar to enhance the arrangement’s ambiance and fill out the sound.

In comparison to the original rock arrangement, Perry’s version of the song features a significantly

larger piano section, and the lead guitar has been entirely reworked to fit the song’s minimalist vibe.
