I’ve found the best sounding guitarless backing tracks and posted them here on Guitar Toys. Just click ‘Guitarless Backing Tracks‘ (you can also always find my favorite backing tracks to the right under ‘Post Categories’).
Here are some other options:
YouTube – YouTube is one of the best places to find backing tracks. Just enter in the search bar the words “backing track”, and either a style, a key, or both, and you’ll find a boatload. Click here. Tip: get the YouTube app and play from your phone or tablet; output the sound to a PA system or amplifier and you’ll be flyin’ high. It is possible to download mp3’s from YouTube if you’re so inclined.
Spotify – Yes, Spotify has some very high quality backing track recordings. If you’ve got a subscription, take advantage and search.
