the use of two ply drum heads. Austrian drummer/clinician Thomas Lang has toured with Sonor's new designer x-ray acrylics to rave reviews for his playing, and for the sound of these drums. In 2010, Thomas Lang stopped endorsing sonor and moved on to DW drums. Changing the overall attitude of drummers concerning the sound of acrylic drums has been a focus of the review media. In 2007 articles and reviews, the magazines gave unabashed praise for the look and sound of modern acrylic drums. Superlatives like "fat" and "warm" were liberally applied. These terms are normally given to wood-shelled drums to indicate that they have abundant low and midrange frequencies. With the right combination of drumheads and tuning, acrylics don't have to sound brittle or artificial. European e-zine www.drummersdigest.com posted a very positive review of a Kirchoff Arctic series solid-cast acrylic kit, to include audio recordings that prove acrylics can sound as musical as other drum shell materials. Ultimately, the difference in tone between acrylic shells, such as the Vistalite shells, and traditional wood and metal shells can be subtle, yet still present. While some acrylic shells have been criticized for their dry, dull tone, others have been raved about for years, such as the shells used by John Bonham. Many drummers, and musicians/recording engineers in general, have a preferred drum sound that they strive to attain when playing and recording, and while some wooden drums have seemed to dominate this recording field throughout recent decades, acrylic shells have still played a keystone role in numerous sought after recordings.
