Backing tracks used to be taboo. Sure, people did it—but they didn’t want to admit it.
However, times change. Big-time touring bands use backing tracks, which has given at least an air of legitimacy. Perhaps an even bigger factor is that with downsizing the norm for live

A switch in a mixer or DAW that allows one or more channels to be auditioned while muting other channels. Some mixers include a separate role bus for routing to monitors of headphones. See also: Exclusive Solo. and duo acts are increasingly common. It’s understood that if there’s no place on stage to set up a drum set, you have no choice for drums other than a backing track.
Of course, some still consider backing tracks akin to cheating. But somewhere between something innocuous like having a drum machineDefinition:
A device that combines sequencing and analog or sampled drum sounds to allow musicians to program repetitive drum patterns. Intended to sound at least somewhat like a human drummer. play in the background, to the cardinal sin of lip-synching to a pre-recorded vocal instead of doing your own singing, there’s a “sweet spot” where you can enhance what is essentially a live performance. For example, a guitar duo might sequence bass lines, or a drummer could triggerDefinition:
A signal that starts an event. pre-recorded ethnic percussion from a drum pad.
There are even alternatives that can enhance your performance without adding backing tracks per se, like the TC Helicon VoiceTone Harmony G XT vocal harmony pedal, which generates harmonies by processing your vocal. Guitarists can use electronic/MIDI guitars, which allow applying an octaveDefinition:
A musical interval based on frequency. Halving or doubling a note's frequency brings it down or up by an interval of an octave, respectively. In Western music, an octave represents 12 semitones. divider effectDefinition:
A device or software program that modifies some aspect of audio or video. With audio, the term is used interchangeably with signal processor. (like the Electro-Harmonix Micro-POG) to the lower strings. This adds a semblance of a bass part.
Regardless of how you decide to enhance your act, remember that we’re dealing with live performance—you need something bullet-proof, easy to change on the flyDefinition:

Backing Track Options
The simplest solution is audio that plays in the background (e.g., a drum machine, pre-recorded backing track from a smartphone or tablet, MP3Definition:
A lossy digital compression coding format for audio, derived from the MPEG-1 and MPEG-2 formats. Audio compression can range from a data reduction ratio of 200:1 to broadcast quality (i.e., no noticeable audio degradation for the vast majority of listeners). MP3 streaming rates vary from 16 kilobit per second to 320 kilobits per second for stereo. Audio stored digitally in the MP3 format will have the .mp3 file extension. player, etc.), while you play the up-front parts. Smartphones are a good choice—as long as you remember to put them into airplane mode before going onstage! The screen can be a little cramped, though, so a tablet is often more error-proof. Several tablet holders can clamp on to mic stands, like the Ultimate Support JS-MNT101 (Fig. 1)
An advantage of storing backing tracks on a tablet or smartphone is that most of them can stream audio via BluetoothDefinition:
A short distance (less than 33 feet) wireless data transfer standard., and many powered speakers designed for live performance (like Bose’s S1 Pro or the Mackie Freeplay-Live; see Fig. 2) have Bluetooth so you can stream right into them.
Some acts still prefer backing tracks on CDs, because if the CDDefinition:
CD (Compact Disc): An optical-based, disc-shaped digital recording and playback medium. player has a remote, calling up backing tracks can be less obtrusive than working a tablet or smartphone on a mic stand. Just make sure you get a commercial-grade unit, with enough anti-skip memory to handle tough live environments. For example, TASCAM’s CD-200BT (Fig. 3) is a sturdy, rack-mount unit with 10-second shockproof memory.
The CD-200BT also has a Bluetooth receiver. Although you can’t stream from the CD-200BT to a Bluetooth-compatibleDefinition:

Laptops for Live Performance
Audio files you created for backing tracks may have started in a computer sequencer, so it may make sense to use a computer to play them back in live performance. This is also the most flexible option; for example, you can sometimes add loopDefinition:
1. To re-record dialog over video. See: ADR. 2. To replay a portion of audio or video content. 3. (sampling) To repeat a section of a waveform so that it can sustain indefinitely. 4. To repeat a phrase or section of sound multiple times within a composition or recording. points on-the-fly, so that a section can repeat if you want to extend a solo. Or, have a couple variations on a track, and muteDefinition:
1. To silence or squelch an audio signal. 2. A switch that silences a signal. the unused ones for different performances so that there are at least some differences between sets.
Regarding reliability, though, few laptops are built to rock and roll specs. Connectors are flimsy, too; at least build a breakout boxDefinition:

Keyboards
Here you have two options. Arranger keyboards are optimized to generate backing tracks, and for some solo acts, that might be all you need. These cover a wide variety of price ranges, all the way up to a high-end keyboard like the Yamaha Genos (Fig. 4).
The Genos not only includes over 500 factory styles, but 1.8 GB of flash RAMDefinition:

RAM is volatile, meaning that all data is lost when power to the RAM is turned off. for storing your own sounds. It has lots of effects, does vocal processing, and can also assemble playlists for automatic playback.
Workstation keyboards are designed as more general-purpose instruments, with comprehensive on-boardDefinition:
A Sound or Lighting Control Console. sequencing instead of a collection of styles and arrangements. The Korg Kronos 6 (Fig. 5) is representative of this option—it has a 61-note, semi-weighted keyboard, and nine different sound engines. But what makes it suitable for backing tracks is the 16-trackDefinition:

Also called MIDI 1.0. sequencing on-board sequencer. When you want your own backing tracks, this allows more customization than typical arrangers.
And Finally...
With live backing tracks, always have an exit strategy. Many years ago, I had a live act based around some unpredictable gearDefinition:

(One piece was a “language lesson” set to music that involved a word we can’t mention here, another had a segment from the “How to Speak Hip” comedy album.)
